The original We-Vibe Sync is one of the few couples vibrators I orgasm with easily and reliably during sex, completely hands-free. It’s up there with the We-Vibe Chorus and We-Vibe Sync 2 and if you can still find it available, it’s usually the most affordable of the three.

Like all couples vibrators, it’s gentler than holding a handheld vibrator to my clit during sex, but it adds extra G-spot pressure, and frees up your hands during sex. The clit and G-spot stimulation together are enough for me, but if you typically need a lot of power to orgasm, the Sync may not be enough. In which case, a wand in the Liberator Axis mount is my favorite hands-free alternative.

The Sync’s two adjustable hinges sit at the base of the clit arm, and on the internal arm, letting me shape the toy to my body. Once I set it, the clit motor maintains good contact without needing to reposition. The fit is much tighter than flexible-only models like the We-Vibe Sync Lite, Sync Go, Lelo Tiani 3, and Dame Eva: those bend, spring back, and shift off my clit.

Keep in mind, C-shaped toys like this are still somewhat dependent on your anatomy to fit right. You can adjust the angle, but not the length of the arms.

The internal arm’s primary stimulation comes from added pressure rather than vibrations, which are very weak. It is thinner and less bulbous than the Sync 2’s or Chorus’s, so I prefer to adjust that second hinge into a pronounced shape for the best internal pressure. Once I have it adjusted properly, thrusting presses the arm into my front wall and makes the stimulation feel fuller and helps me orgasm.

Comfort during sex is excellent. The slim internal arm leaves enough room for penetration, does not pinch or poke, and feels slightly gentler than the more pronounced arms on the Sync 2 and Chorus. My partner feels the arm’s vibrations, but they have stayed subtle enough to be neutral for him rather than distracting or overstimulating, and entry feels snug without being too tight.

All 3 are great picks for during-sex use. Go with the Sync for the most affordable option and slightly slimmer internal arm, which may be more comfortable to some. Or choose the newer Sync 2 or Chorus if you want a slightly thicker internal arm for more G-spot pressure and a fuller feel.

In the next sections, I’ll cover the Lucy’s vibration power and rumbliness in detail.

Here’s the main conclusion: The Lucy is one of the most stimulating panty vibrators I’ve tested, especially for its price – strong, with a form-fitting design that delivers that strength to your clit well. The trade-off is rumbliness – the Lucy is buzzy at every setting, and extremely buzzy at the top, but I still enjoy its vibration feel personally.

If strong, rumbly vibrations matter more, go with the VeDO Niki (remote-only, no app), but otherwise the Lucy’s clit stimulation is great.

In the next sections, I’ll cover the Sync’s clit vibration power, range, transfer, and rumbliness in more detail.

Here’s the main conclusion:

The original We-Vibe Sync is tied with the Sync 2 and Chorus for the most effective clit stimulation I have gotten from a couples vibrator worn during sex. Its motor is only moderately strong, but the adjustable fit keeps that strength pressed against my clit, so the vibes transfer well.

The Sync is not the right choice if you mainly want maximum clit power outside of sex. Stronger panty vibrators and handheld toys feel more intense. But amongst couples vibrators, the Sync’s combination of consistent contact, gradual power adjustability, and moderately deep vibrations works very well for me.

The Techno Lucy is one of the strongest panty vibrators I’ve tested, with a top power of 9 out of 10. Among magnetic panty vibrators, only the Lovense Ferri reaches a higher top strength.

The power range is wide, but there’s only three power levels: a soft 1 out of 10 at the low end (a good warmup setting), a jump straight to 7 in the middle, and a powerful 9 at the top. While there’s not a ton of intermediate settings, I personally find the three settings it provides enough to comfortably warmup and finish strongly.

The Lucy also transfers that power to your clit really well. Its curved, broad design contours to your vulva, and a strong, wide magnet keeps the toy from pivoting out of place. Among magnetic panty vibrators, only the Lovense Ferri delivers more of its motor’s strength to your clit. While a lot of panty vibrators feel weaker than their strength would suggest, the Lucy’s 9 out of 10 power actually feels strong on your clit.

The Lucy’s curve also gives you some ability to press the vibrations more firmly into your clit hands-free. When you’re sitting, shifting your weight onto the end opposite your clit tilts the front end more firmly into you – closer to handheld pressure control than a straight panty vibrator gets, though still certainly not the level of pressure you get from a handheld vibrator.

The Sync’s clit motor is only moderately powerful but very effective for a couples vibrator because it transfers that power well. It starts gently and reaches 6.75 out of 10 on high.

That’s weaker than other wearable vibrators overall (like the Lovense Ferri), but it’s some of the strongest I’ve found in C-shaped couples vibrators: tied with the Chorus and Sync 2.

Couples vibrators like these rely on a combination of moderate clit vibrations, plus added G-spot pressure during penetration to build enough stimulation for orgasm.

What the Sync does well is transfer that clit’s motor strength to my body. The adjustable hinge holds the external arm against me snugly. The hinge at the base of the external arm is most important for this, but there is also a second adjustable hinge on the internal arm.

The Sync has a wide range of power. It starts at a very gentle 0.25, and climbs through 13 levels to full power. That gives me a slow build with gradual steps.

Unlike several newer We-Vibe models, the Sync reaches both its gentlest setting and true top power from the app. Unfortunately the Chorus and Sync 2’s top strengths are capped in the app.

But the Sync is one of the most stimulating couples vibrators I’ve tried, and one of the most affordable since it’s an older model.

We rate rumbly vibrations higher than buzzy ones because it’s what most people prefer – rumbly vibrations travel deeper and feel more diffuse, while buzzy ones stay nearer the surface with a sharper kick. But this is a personal preference, and many people do enjoy buzzy vibes.

The Lucy is buzzy. Its lowest setting measures 92.5 Hz, which is moderately buzzy, and the top climbs to 142.5 Hz, well into the extremely buzzy range. There’s no level where the Lucy feels rumbly or even neutral – its vibrations stay in the moderately-to-extremely buzzy range across all three settings.

This is fairly typical for panty vibrators – the small motors that fit inside a wearable often have a hard time generating the low-frequency vibrations that feel rumbly while also spinning fast enough to feel strong. I personally enjoy the Lucy’s strong, buzzy vibrations, because they stay pressed to my body and transfer well to my clit.

But if you want a strong, rumbly panty vibrator, the VeDO Niki is a great option for about $20 more. It’s a rare panty vibrator that delivers deep, low-frequency vibrations throughout its whole power range.

The Sync’s clit vibrations are fairly deep for a wearable at the lower and middle settings, but they turn buzzy at the top. If you enjoy some buzzy vibrations, this gives you a nice range of options, but the newer Sync 2 is more rumbly on higher strengths.

At the lowest settings, the Sync’s motor is extremely rumbly, though those levels are mostly useful for warming up. The middle of the range sits around 80 Hz, which feels neutral rather than distinctly rumbly or buzzy. That depth helps the moderate power feel more substantial, because lower-frequency vibrations travel farther into the body than sharp surface-level buzz.

The highest setting climbs to 111 Hz, which is extremely buzzy. Vibrators usually get buzzier as they get stronger, but the Sync crosses further than its siblings: the Sync 2 stays neutral, and the Chorus only reaches moderately buzzy.

The Sync has a faint rhythmic tapping layered over the steady vibration, especially on gentler settings, but it is subtle compared to the Sync 2 and Chorus. If rumbliness is your priority, the Sync 2 is the better choice.

Like all panty vibrators, the NS Novelties Techno Lucy only stimulates your clit – not your G-spot. Since most women need clit stimulation to orgasm, a panty vibrator is often the right type of wearable. But if you’re interested in G-spot stimulation instead, see all our recommendations for the best egg vibrators here.

In the next sections, I’ll cover the Sync’s G-spot vibration power, transfer, and rumbliness in more detail.

Here’s the main conclusion:

The original We-Vibe Sync’s G-spot stimulation is minimal on its own but useful during sex. The internal motor is very mild and buzzy, which is common for couples vibrators because you get more stimulation from the added G-spot pressure during penetration rather than the vibes.

The Sync’s internal arm is thinner and less bulbous than the Sync 2 and Chorus arms, so it takes more hinge adjustment to get it how I want it. But once you find your right fit, thrusting presses the arm into my front wall and adds the kind of pressure that makes the toy feel more stimulating than clit-only models, like the Sync O.

If you want strong, rumbly G-spot vibration for solo play, choose an egg vibrator or a larger dual-stimulation toy like the Lovense Dolce.

But for use during sex, the Sync is great.

The Sync’s G-spot motor is very mild, which is normal for hands-free couples vibrators. It tops out at 1.25 out of 10, less than one-fifth of the clit motor’s 6.75 and one of the gentlest internal motors of any wearable I have tested.

The 13 levels are so gradual, I can barely distinguish one step from the next.

But every hands-free couples vibrator I have tested has a gentle internal motor, including the We-Vibe Chorus at 2.50, the Sync 2 at 2.75, and the Chorus Pro at 3.25. The internal arm’s stimulation is more about added G-spot pressure than vibrations.

Used solo, the Sync’s internal vibrations feel weak and diffuse. During penetration, the bulbous shape presses firmly against the front wall as my partner thrusts. That pressure helps me orgasm hands-free.

If you value G-spot vibrations more and don’t need to use it during sex, an egg vibrator like the Lovense Lush 4 is much stronger internally.

The Sync is great for those who want some extra G-spot pressure and are specifically looking for a hands-free toy to wear during sex.

The Sync’s internal vibrations are buzzy, especially past the lowest settings. That is typical for a slim couples-vibrator arm.

The lowest settings sit around 72 Hz and feel moderately rumbly, but they are also very gentle. The middle and upper settings climb quickly into the extremely buzzy range, with a median around 139 Hz and 203 Hz on high.

Used solo, that buzziness is one reason I barely register the internal vibrations: the G-spot is less sensitive than the clit, and buzzy vibrations need more power to compensate. During sex, the pressure from the arm is what makes the stimulation meaningful, so the buzziness doesn’t bother me.

If you want strong, rumbly internal vibration on its own, an egg vibrator like the Lovense Lush 4 is the better fit.

In the next sections, I’ll cover the Love Spouse app’s close-range and long-distance features and its connectivity in detail.

Here’s the main conclusion:

The Love Spouse app is very basic and can feel spammy. But it’s functional for both close-range and long-distance play. The Techno Lucy is also more sensitive to body interference blocking the bluetooth signal than pricier panty vibrators. But at this budget point, it’s a good option.

If you want a feature-rich app and the best connectivity available, you’ll need to increase your budget and go with the Lovense Ferri. If basic, working app control is fine, the Lucy’s app does the core job.

In the next sections, I’ll cover the We-Vibe app’s close-range features, long-distance features, and connectivity in more detail.

Here’s the main conclusion: The We-Vibe app is the Sync’s biggest weakness. It has good features on paper, and the Sync’s Bluetooth signal is strong, but the app is buggy and controls freeze often enough that I would not rely on it.

If app control matters more than hands-free use during sex, a Lovense toy such as the Ferri (clit stim), Lush 4 (G-spot stim), or Dolce (dual-stim) is a better choice, though none of those are wearable during sex. We-Vibe makes the only good couples vibrators I can orgasm with, so if that’s your goal, the Sync is still worth choosing – I’d just skip the app and use the remote or on-toy button.

The Love Spouse app’s close-range features are very basic – it has the most limited close-range app experience I’ve tested in a panty vibrator. The core constant-intensity control works, so if you just need an app to select your vibration power it’s fine – especially at this budget. But more customized controls you’d expect from higher-end apps are either missing or don’t work well. Consider the Lovense Ferri if you care about greater customization.

The one useful screen in the app is Classic Mode, which lists the toy’s preset modes as “Mode 1” through “Mode 9.” Modes 1-3 are the toy’s low, medium, and high constant intensity; the rest are the toy’s preset patterns.

That’s the entire intensity-control system – three stepped levels rather than the continuous adjustment most panty-vibe apps offer. If you want to dial in a precise feel between low and medium, you can’t; you’re stuck with the three steps the toy ships with. The modes also aren’t descriptively labeled, so you (or a partner controlling your toy) can’t tell what a pattern feels like without trying each one first, you have to memorize what each means.

Beyond Classic Mode, the app is cluttered with poorly built features that don’t add value. Draw Something is meant to let you drag your finger on the screen to control vibration intensity – but the response is so inconsistent that after ten minutes I still couldn’t figure out how it was supposed to work. Music Mode plays the toy along to music, but you’re limited to a handful of pre-installed songs the brand made up – no Spotify, no Apple Music, no songs from your phone – and the vibrations don’t really match the music anyway. Game Mode and a Shaking feature (where you shake your phone to control intensity) are similarly unusable in practice. Ads for the brand’s cam services run throughout the app, often taking up more space on the main control screen than the controls themselves. You don’t have to watch ads before playing, but they’re on the screen taking up space.

If you want anything beyond stepping between three preset intensity levels or selecting from the preset patterns the Lovense Ferri has a much better app. If you’re fine with basic controls and just need a functional app on a budget, the Techno Lucy’s app can be fine.

The We-Vibe app’s close-range features are weak because the app is so buggy. If it worked properly, it would be a decent option for simple intensity control and preset patterns. But the current experience is frustrating.

The main controls are Single Vibe and Multi Vibe. Both let you drag an on-screen dot up or down to adjust intensity. And unlike the newer We-Vibe Sync 2 you can access the Sync’s true top power through the app.

Multi Vibe also lets you assign preset patterns to four corners, so you can quickly switch between steady vibration and a few favorite patterns without digging through menus. On both screens, you can adjust the clit and G-spot motors together or control them independently. The design is simple and convenient in theory.

But the control dot often freezes or stops responding – this happens even more often when you try to control the two motors independently.

There are 10 preset patterns you can choose from in Single or Multi Vibe mode, each with a name and waveform icon. Some are easy to understand, like Pulse and Wave, while others are less clear. There’s also a Playlist feature for stringing patterns together, but you can’t feel what you’re building as you make it, so it’s mostly guesswork.

Custom pattern creation is poor. It’s hidden several taps away from the main control screens, and you can’t feel the pattern while drawing it. You have to draw the waveform, save and name it, return to the control screen, select it, and only then test how it feels. The patterns are also limited by your screen width, so they come out short and choppy. My partner’s custom pattern played, but mine crashed the app repeatedly.

The sound and music modes are okay. Sound Mode uses your phone’s mic, while Music Mode syncs to songs saved locally on your phone – not Spotify or Apple Music. Both work, but the controls are poorly labeled, and there’s no minimum-volume threshold like Lovense offers, which is helpful in preventing your toy from vibrating until the sounds around you are loud enough.

For close-range control, I’d use the Sync’s remote instead of the app. If you mainly want excellent app control, Lovense is much better – choose the Lovense Ferri for clit stimulation, the Lovense Lush 4 for G-spot stimulation, or the Lovense Dolce for dual stimulation. But none of those are couples vibrators to wear during sex. We-Vibe makes the only good couples vibrators I can orgasm with, so if that’s your goal, the Sync is still worth choosing – I’d just skip the app and use the remote.

The Love Spouse app’s long-distance features are basic but functional – the core call-and-control flow works, but getting to the call is rough.

Your long-distance partner controls your Lucy with the same Mode 1 through Mode 9 preset selector you have during close-range play, and the same limitations.

Getting into a call is unintuitive at first, especially if you want to control a partner’s toy without also owning a toy of your own. The easiest way to connect with a partner is to select YOUR own toy from the home screen. Once connected to your toy, you’ll see a “Friend Control” option in the menu. Add your partner, and then you can select to invite them to a control session. Then once in a control session, you can also request to start a video call. This way requires that you also own a toy in order to access your friends list through your toy’s menu.

If you don’t own a Love Spouse toy too, you have to navigate to the “World” menu, which takes you to a spammy screen with a ton of random users sending a constant stream of messages. But in the top left of this screen, there’s a message icon where you can access your friends list and start the video call with your partner from there.

Once you’re in, though, the video call itself is pretty good. Video quality is high on decent internet, your view of your partner fills most of the screen without the controls cluttering the feed, and the toy control panel is easy to access – toggling off fullscreen brings the controls up in the bottom half of the screen while keeping your partner in view at the top. You can also both control each other’s vibrations during the call.

The call does have a few notable gaps. You can’t toggle off your camera or mute your mic – only flip front/back camera, switch to speaker, or end the call (a voice-only call option exists as a fallback). And there’s an in-call messaging feature that you should not use: messages fill up the video screen and don’t go away.

The standalone chat experience is bad: messages appear in a tiny corner window, text overflows onto buttons of similar color, lines cut off mid-word, and there’s no message history. There’s no media sharing during an active control session either – you can’t send a photo or voice clip while controlling your partner’s toy.

For people interested in the Anonymous play some higher-end apps like Lovense offer, it exists in the Love Spouse app, but it’s behind a paywall.

If long-distance play is a priority for you, the Lovense Ferri is a better choice – its app gives your partner rich control in long-distance mode, with a clean non-spammy interface that works well. For basic control over your partner’s vibrations during a video call, the Techno Lucy can work fine.

The We-Vibe app’s long-distance features are too buggy to recommend.

The design is decent in theory, but persistent connection and control issues make long-distance play unreliable. If long-distance control matters there are no good couples vibrators – you’re better off with a different type of wearable. The Lovense Ferri for clit stimulation, the Lovense Lush 4 for G-spot stimulation, or the Lovense Dolce for dual stimulation are better long-distance options.

Long-distance control in We-Vibe’s app is supposed to work like close-range control. Your partner gets the same Single Vibe, Multi Vibe, and Touch screens to control your Sync, and you can control their toy the same way. You can also take back control of your own toy mid-session without ending the call, which is a useful feature.

But the same close-range bugs carry over: the control dot sometimes freezes or stops responding. And most importantly, both partners often show as “offline” even when you’re both in the app, which prevents you from starting a session at all.

Even when it does connect, starting a video call is clunky. You have to send and accept four separate requests: the call, camera access, control of your toy, and control of theirs. The video feed is blurry and choppy compared to Lovense.

Chat works as a basic messenger, with text, photos, voice notes, and video clips. We-Vibe does let you save multiple partners, but it doesn’t offer Lovense’s anonymous one-time control links or auto-accept settings for trusted partners.

One area the Sync is better than the newer models: you can access the Sync’s true top power through the app, unlike the newer We-Vibe Sync 2. So your partner will have access to the full power range when the connection works.

For long-distance play, a Lovense toy like the Ferri, Lush 4, or Dolce is far better, but they don’t have any couples vibrators to wear during sex.

The Lucy’s app connectivity is reliable for solo control, but it’s just decent for nearby or long-distance partnered play. If reliable connectivity through any situation matters a lot to you, the Lovense Ferri is a better option, though it’s pricier.

Getting up and running is mostly automatic. The very first time, you have to enter a four-digit binding code from the toy’s instruction manual – annoying, but you only do it once (so don’t toss the manual before pairing). After that, the app auto-connects whenever you open it and turn the toy on. If the connection drops mid-session (like from going out of range), reconnection is automatic as soon as the signal’s clear again.

When I’m controlling my own toy, commands go through reliably and the connection holds through phone locking, app-switching, and periods of inactivity. The Lucy can also handle light body interference, like controlling the toy yourself or when a partner is facing you or at a slight angle. But as you put more of your body between the phone and the toy, it can lose the connection.

Water-rich materials like body tissue can significantly dampen bluetooth signals – much more than clothes or typical walls. Our body-interference test simulates this at three progressively harder positions: the Lucy holds a stable connection at the first, drops occasional commands at the second (but auto-reconnects on its own), and can’t maintain a connection at the third, most severe angle.

The Lovense Ferri holds at all three positions, which matters if a partner will be controlling your toy with a lot of your body in the way.

The Lucy’s Bluetooth range comes in around 40 feet in our open-air test, measured with a clear line-of-sight. That’s enough for same-room control, but well short of what Lovense’s and other panty vibrators reach – and body interference at certain angles will shorten your real distance further.

For long-distance play, the connection works well when both partners keep the Love Spouse app open. Sessions don’t drop unexpectedly, and commands go through reliably while both apps are active. If the toy-wearer’s app is locked or minimized, it can cause the controls to freeze until the app is back up again. Better long-distance apps like Lovense’s let the controlling partner keep adjusting your vibrations through normal phone behavior.

For solo control, partnered control from angles without much of your body in the way, and basic long-distance play, the Lucy’s connectivity holds up – especially considering how inexpensive the Techno Lucy is.

The Sync’s app connectivity is poor even though the toy’s Bluetooth signal is strong. The issue is the glitchy We-Vibe app, not the signal itself, which is why similar problems show up across all We-Vibe couples vibrators.

In our Bluetooth tests, the Sync’s app connection handled body interference well. The test simulates body interfernce at three increasingly difficult angles, and the Sync stayed connected through all three. Its open-air range reached 200 feet in a clear line-of-sight range test, which is more range than you need for a toy used during sex.

Pairing is not hard, but it is more cumbersome than it should be. You swipe to the Sync in the app’s toy carousel and tap Connect. The app walks you through holding the toy’s button until it vibrates twice, though I can usually tap “Done” and skip that step.

When quick connect fails (especially with multiple We-Vibe toys or two phones in the mix) recovery can mean forgetting the toy in phone Bluetooth settings, deleting it from the app, and pairing from scratch.

Reconnection is inconsistent. If I come back into range within about 10 to 20 seconds, the app often reconnects by itself, but it does not clearly tell me the connection dropped while it is happening. That means a partner can keep dragging the control dot while nothing reaches the toy. After a longer drop, the app shows a disconnect message and requires a manual reconnect, sometimes with a press on the toy’s button.

Long-distance connectivity is worse. Both partners can show as offline while both are active in the app – when this happens you can’t connect at all and we’ve found no reliable workaround. Even when sessions start, commands often stop reaching the toy mid-session. All these bugs make the Sync a bad choice if app control is a main priority.

The NS Novelties Techno Lucy doesn’t include a physical remote control. A remote lets you adjust the toy by feel – without pulling out your phone. Though there’s other downsides like less depth and no visual feedback to help your partner know what your toy’s doing. If you want to consider options with physical remotes, see our recommendations in these guides:

• best remote and app-controlled vibrators (all types of vibrators)
• best wearable vibrators (wearables only).

In the next sections, I’ll cover the Sync’s remote features and connectivity in more detail.

Here’s the main conclusion: The Sync’s remote is good during sex, though not the best for a partner controlling your toy as you wear it around.

It has some issues with body interference missing commands when a partner controls your toy from behind you or at an odd angle – this mainly happens if you’re wearing the toy around, but isn’t really an issue when controlling it during sex from really close.

If a partner controlling your couples vibrator is important to you, the Chorus’s remote did not have any issues with body interference.

The We-Vibe Sync’s remote provides good, basic controls.

The best feature is separate power and pattern control. Dedicated buttons move through 13 power levels, and a second pair of buttons moves through the 6 vibration patterns. That means I can turn intensity down without cycling through patterns first. Pressing and holding the top button jumps to full power; holding the bottom button turns the toy off rather than dropping to the gentlest setting.

The remote also lets you raise and lower pattern intensity. The Sync’s 13 levels give the clit motor a gradual build. The remote controls both motors together, though. If you want clit and G-spot motors at different intensities, you have to use the app.

The remote itself is a slim hard-plastic oval. It fits easily in my hand, and the raised buttons have enough of a raised feel that I can use them without looking. The newer Sync 2 remote feels more polished and comfortable because it is silicone.

The feedback is weak for partner control. Like most remotes, the Sync’s just blinks when you press a button, and its blink is faint. It keeps blinking even when the toy is off, so it does not reliably tell the person holding it what is happening. That is fine when I am controlling it myself, but if a partner’s controlling, it doesn’t give them a good idea of what setting I’m on.

The Sync’s remote connection is reliable when I hold it myself during sex, but it has the shortest range in We-Vibe’s couples line and struggles when your body blocks the signal, which can happen when a partner controls your toy.

Body tissue is the main problem for remote control because water-rich tissue absorbs RF and Bluetooth signals. Our body-interference test simulates this interference at increasingly difficult angles (and is harsher than real use). The Sync held steady at the easiest angle, missed about half the commands at the middle angle, and became unreliable at the hardest angle until I brought the remote closer. The We-Vibe Chorus is the only couples vibrator in the line whose remote held through all three; the Sync 2 behaves about like the Sync.

That weakness does not usually show up when I use the remote myself. It stays close to the toy with a clear enough path, and commands go through reliably. The response is slightly slower than the quickest remotes I have tested, landing just after my finger leaves the button, but not slow enough to be annoying.

The open-air range was about 22 feet with clear line of sight, compared with about 38 feet for the Sync 2 and 40 for the Chorus. Real rooms and bodies shorten that. But the remote works fine when the Sync is close by during sex. The issues don’t start until you hand the remote to a partner while wearing the toy around.

Like most panty vibrators, the Lucy’s on-toy controls are limited by design – the toy sits inside your underwear during use, so you’ll typically rely on the app.

There’s a single button on the toy that cycles through the same nine settings from the app – three steady power levels, then six vibration patterns. There’s no minus button, so dropping back to a gentler power takes cycling through the remaining settings. Nine settings is enough that the cycle takes some patience, but as a backup or if you want to occasionally use the toy handheld it works fine.

The button is well-placed: easy to feel and press without looking, and centered in the middle of the broad, plush body. Pressing it does push the toy against your vulva, but the central placement and broad surface distribute the pressure evenly across your body rather than concentrating it in one spot, so it’s comfortable.

The limited on-toy button works fine, since the app is the main way you’ll use the Lucy.

The Sync’s on-toy controls are basic but usable. A single button cycles through 4 power levels and 6 vibration patterns on one loop, so dropping back to a gentler power means clicking through whatever patterns remain. I rarely want the patterns, but the 4 power levels cover the full range and keep the loop short enough for occasional use.

The button is easy to find by feel because it sits on the external arm, has a distinct feel, and does not require removing the toy. Pressing it can push the toy firmly against your pubic bone unless you brace the other side with a thumb, and the older slim button is a little less comfortable than We-Vibe’s newer rounder buttons, but is still workable.

I like the button most as a backup during sex. When I am warmed up and want more intensity, reaching between my legs for one click can be easier than reaching for the remote or opening the app.

The NS Novelties Techno Lucy is the most secure fitting panty vibrator I’ve tested, even compared to other magnetic panty vibrators.

The clit-end is broad, but it tapers narrower toward the base between your legs, the toy curves to be form-fitting along your vulva, and the magnet is strong, large, and recessed into a divot at the back.

The broad clit-end paired with the large magnet pins the part vibrating by your clit firmly to your underwear. It has none of the wiggle room a narrower toy or small magnet sometimes leaves. Even if the toy tilts slightly as you move, the breadth of the clit-end keeps it secure against your body. And the curved, tapered shape means your thighs don’t bump the toy off-axis as you walk – it nestles naturally between your legs.

In bed, the toy doesn’t shift through normal moving around or changing positions.

During light activity like walking or doing chores, you can feel the toy move with you as you walk, but it doesn’t actually shift off the spot you secured it to – and gravity doesn’t pull it down off your clit even when standing.

Heavy activity is where most magnetic panty vibrators shift more, but the Lucy holds up better here than any I’ve tested. It stayed in place and maintained great clit contact while I danced and did high knees. Jumping and running do make it bounce – the toy pulls away from your body when you land – but it moves right back where it’s clipped without any manual readjustment.

In this section, I’ll cover the Sync’s fit for solo use in bed, walking around, and heavier movement. For fit during sex, see Hands-Free Use During Sex.

The Sync stays put well enough for bed and light activity, but wearing it around is still a secondary use. Its C-shape is designed to be worn during sex, not movement-heavy play.

The two adjustable hinges are very helpful in finding a good fit. One hinge sits at the base of the clit arm and one in the internal arm, and both hold the shape I press them into.

This is a huge difference from merely flexible couples vibrators, which don’t hold the shape you set. An adjustable hinge is essential in a couples vibrator because it lets me tighten the clit contact instead of hoping the toy’s default curve works. Flexible-only models like the Sync Go or Sync Lite shift off my clit immediately when I’m moving around.

But the adjustability is limited to angle. The fixed clit-arm length still matters: if that arm does not reach your clit, no hinge setting can fully solve it.

The Chorus also has two hinges, while the Sync 2 has one, but I can find a secure and stimulating fit with all 3.

In bed, the Sync does not shift when I roll side to side or onto my stomach. The internal arm is slimmer than egg vibrators so it can feel less-secure, but it has not slipped out for me.

During light activity, including walking, stairs, and chores, it stayed put. Snug underwear plus shorts are helpful if you’re out of bed and moving around. Heavier movement is where you’ll encounter issues: dancing, running, and high knees were fine, but jumping jacks made it wiggle loose far enough that I had to push it back up.

If active wear matters more than sex, the Sync O is more secure because its flexible loop anchors differently, though it is less stimulating during sex. For wearing arout of bed as the main use, an egg vibrator or magnetic panty vibrator is a better pick, but not wearable during sex.

The NS Novelties Techno Lucy is the most comfortable panty vibrator I’ve tested. It stays comfortable both in bed and while you’re up and moving around – where most panty vibrators drop in comfort to some degree when walking.

The same design that makes it fit so securely also keeps it comfortable. The broad clit-end distributes pressure evenly across your clit area, the slim section between your legs prevents it from getting bumped around much with movement, and the form curves to stay snug against your body.

In bed, the contours extremely well to the body. Like the Sexy Secret, it’s the easiest panty vibrator I’ve found to settle into a comfortable placement, but the Lucy is far more stimulating.

During light activity like walking around the house or sitting at a desk, the broad, plush surface keeps good contact with the clit without any uncomfortable “tapping”, even if the toy is jostled a bit. When sitting, the extra pressure distributes evenly across the plush surface. The Lucy is one toy I could wear for a long time without becoming uncomfortable.

This section covers comfort during solo use in bed and while wearing the Sync around. For comfort during sex, see Hands-Free Use During Sex.

The We-Vibe Sync is one of the most comfortable C-shaped couples vibrators I have tested. Its adjustable hinges let it sit snugly without clamping too hard, and neither arm pinches, pokes, or creates pressure that makes me want to remove it.

The external arm is broad enough to spread pressure across my body instead of concentrating it in one spot. The internal arm is slimmer than a large egg vibrator, so it does not add a distracting stretch, and the silicone feels smooth.

In bed, the Sync stays firmly against me without uncomfortable pressure. I can wear this much longer than an egg vibrator without feeling too stretched. Walking around, it does not jostle, rub, or make me change my gait.

The adjustable We-Vibe models are all strong here: the Chorus, Sync 2, and Sync O are similarly comfortable.

The Lucy is exceptionally quiet – tied for the quietest panty vibrator I’ve tested. And unlike the others tied with it (Satisfyer Sexy Secret, Little Secret, and Romp Party), it’s also one of the most stimulating.

Decibel readings on low and high power were extremely quiet, too quiet for my Sound Level Meter to pick up. The ambient room noise was 35 dBA, and the Lucy never measured higher than this.

The Lucy is also in the most discreet tier of wearable vibrators I’ve tested in our Background Noise Masking subtest. In this subtest, I wear the toy while my partner listens from three feet away and we play pink noise through a speaker at quiet, moderate, and loud volumes (56, 62, and 68 dBA). He couldn’t hear the Lucy at any vibration strength while playing any of our three volumes of background noise audio. It’s definitely audible in our room without any background audio playing – but every wearable vibrator I’ve tested is, no matter how gentle and quiet the vibrations are.

Behind a closed bedroom door, the Lucy was similarly inaudible. For this part of the noise test, my partner listens from outside the closed door while I use the toy in bed. I use it like a handheld toy since wearing dampens sound, and some people want the flexibility to safely reposition the toy or move it around. Holding the toy instead of wearing it gives us the most conservative results. He couldn’t hear the Lucy at any setting from behind our bedroom door – no fan or music needed to mask it.

The We-Vibe Sync is very quiet – in the most discreet group of wearables I have tested, and I can barely hear it while wearing it.

On low power, the Sync never rose above our room’s 35 dBA ambient noise, so the sound meter could not separate the toy from the room. On high, it measured about 42 dBA, which makes sense given the buzzier top end, and is still quiet. The Sync 2, which stays more neutral in vibration frequency is even quieter on high.

In our background-noise masking test, my partner listened from three feet away while I wore the toy and we played pink noise at 56, 62, and 68 dBA. He could not hear the Sync at any vibration strength under any of those conditions. In a silent room, it is audible, but every wearable vibrator we have tested is audible in a silent room.

Behind a closed door, the Sync passed easily. My partner heard nothing from outside the bedroom while I ran the toy through every power level and pattern. I held the toy for that test instead of wearing it because wearing dampens sound, so holding it gives the more conservative result.

Most hands-free couples vibrators we have tested are similarly discreet, including the Sync 2 and We-Vibe Chorus.

The Lucy has a short battery life – it lasted 55 minutes in my test on its highest setting. That’s lower than high-end panty vibrators – the average runs closer to 90 minutes, and the Lovense Ferri lasts closer to three hours. You can extend the Lucy’s battery life during normal use since you’ll likely also use the lower settings some too.

The We-Vibe Sync lasted 85 minutes vibrating continuously on its highest power in our test. That is plenty for sex, and real use should last longer if you spend part of the session on lower settings.

It also outlasts the two pricier couples vibrators I also recommend: the Chorus lasted 65 minutes, and the Sync 2 lasted 63. The Sync O runs longer at 93 minutes, but it is less stimulating for me during sex.

Wearables designed specifically for out of bed use last longer, like the Lovense Ferri (168 minutes). But the Sync is plenty for use during sex.

The Lucy is easy to clean. It’s fully IPX7 waterproof, so you can clean it under a running faucet or fully submerge it in soapy water without worry.

The We-Vibe Sync is very easy to clean. The toy itself is fully waterproof with an IPX7 rating, so you can rinse it under running water or fully submerge it in soapy water and scrub the arms, hinges, and charging contacts without worrying about damage. You can also take the toy into the bath.

The remote needs more care. It is IPX4 splashproof, which means it can only resist light splashes. Do not take the remote into the shower or clean it under a running faucet; wipe it with a damp towel instead.

The Lucy feels high quality, especially for a budget panty vibrator. It’s covered entirely in thick-feeling silicone with a nice flex to it, the button presses with a satisfying click, and the broad, strong magnet creates a solid, sturdy connection.

The We-Vibe Sync feels solidly built, though the remote feels cheaper than the toy. The toy itself is coated in smooth silicone, both hinges still hold firmly when I press them into position, and the joint between the two arms feels sturdy enough that I have never worried about snapping it.

The remote is the older hard-plastic We-Vibe version rather than the silicone remote that comes with the Sync 2. It feels less premium, and the buttons are a little tacky to press, but they work.

I’ve had my Sync since 2022 and it still works like it did when it was new. Nothing has loosened, and both hinges still hold the positions I set. It’s held up better than the pricier Chorus, whose internal arm stopped vibrating and hinges loosened at about the same age.
