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 Flexer’s clit vibration power and rumbliness in-depth.

Here’s the main conclusion: the Flexer provides some of the more-intense clit stimulation out of the dual-stim wearables I have tested, and I can orgasm with it hands-free. The vibrations are buzzy and the flexing motion on your clit can be overstimulating at times though.

If more consistent clit pressure and rumbliness matters most, go with the Lovense Dolce, which doesn’t have a movement motor. If you’re interested in the motion and enjoy buzzy vibes, stick with the Flexer.

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 Flexer’s clit motor is very strong, reaching 9.1 out of 10 on high – one of my strongest wearables. And it still starts gently enough that I can warm up before using the stronger settings.

With wearables, strong motors only matter if the toy keeps that motor in contact with your body. In bed, the Flexer does that well, but in a unique way: When the flexing motion is active, the external arm moves back and forth, varying the clit pressure. This makes the stimulation feel stronger and more interesting to me as the external arm presses those vibrations firmly into my clit.

The Flexer is a good fit if you like movement and intensity shifts, but some will prefer consistent contact instead. If you want a dual-stimulation toy that stays in one spot and a more controlled feel, go with the vibration-only Lovense Dolce. The Lelo Ida Wave’s clit stimulation is also more consistent and rumbly while also providing G-spot stimulation from motion.

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.

We generally rate rumbly vibrations higher because most people enjoy them more, but buzzy versus rumbly is still a preference. The Flexer’s clit motor is for people who like strong, extremely buzzy intensity. It’s actually my buzziest dual-stimulation wearable.

The clit vibrations range from 139.59 Hz on low to 244.51 Hz on high – extremely buzzy throughout its entire range. The two vibration motors create a faint wobble sensation when they play off each other, which adds some complexity. But the Flexer is not at all rumbly.

If buzzy vibrations feel tickly or numb to you, the Lovense Dolce or Lelo Ida Wave are better.

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 Flexer’s G-spot vibration power, rumbliness, and flexing motion.

Here’s the main conclusion: the Flexer’s G-spot stimulation is good for a dual-stim wearable, but the flexing motion contributes less than you’d expect. The external arm moves more than the internal arm with each flex, so you can feel some internal pressure, but it’s gentle.

Thankfully, the bulbous design transfers the vibrations well to the front wall. So the combination of internal vibes and gentle movement combines for an enjoyable experience.

But handheld vibrators provide much firmer front-wall pressure since you can leverage the base with your hand. Two of my favorites are the We-Vibe Nova 2 and Lovense Nora.

The Flexer’s G-spot vibrations reach a moderate 4.9 out of 10 strength that enhances the experience when paired with the toy’s external vibes and flexing motion. I’m able to orgasm with the Flexer when the internal and external vibrations work together with the flexing motion.

But, the Lovense Dolce’s internal arm has nearly double the vibration strength of the Flexer. Both have an excellent, bulbous design that transfers the vibrations efficiently to the front wall.

If you find even gentle internal motion more stimulating than vibrations, the Flexer is a great option. If you don’t need motion, and feel stimulated from internal vibrations alone, the Dolce will feel the strongest to you.

We rate rumbly internal vibrations higher because they tend to feel deeper, though some people enjoy buzzy stimulation. The Flexer’s G-spot motor stays extremely buzzy across its entire range, from 182.44 Hz on low to 257.18 Hz on high.

Buzzy vibrations don’t travel as deep, so the buzzy vibrations at only a moderate strength on the Flexer definitely need the internal motion and external vibes to feel worthwhile.

If rumbliness is a priority, the Lovense Dolce is a much better pick.

The Flexer’s motion is enjoyable, but it feels more like subtle internal pressure changes than the firm G-spot fingering that’s advertised.

The internal arm moves in a front-to-back arc at 34 to 63 cycles per minute. The flexing hinge is very strong, and doesn’t “give” under pressure like the flexible Lelo Ida Wave’s internal arm does. However, because there’s no “anchoring” point for the Flexer, the external arm moves more than the internal arm, causing the G-spot pressure to feel gentle. You really feel most of the motion on your clit.

I can orgasm with the Flexer when the motion is paired with clit vibrations and internal vibes. But handheld toys provide firmer internal pressure if that’s a big priority to you. The We-Vibe Nova 2 is great if you want to leverage the pressure yourself. And the Lovense Nora is better if you want automatic internal motion.

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 Lovense app’s close-range features, long-distance features, and connectivity in detail.

Here’s the main conclusion:

The Lovense app is by far the best of any brand. It provides the most control, is easiest to use, and has the most reliable connectivity. If an outstanding app is your top priority, stick to a Lovense toy.

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 Lovense Flexer’s app has the best close-range features of any brand.

On the main Remote screen, you drag the control dots up or down to adjust intensity of the vibrations and speed of the flexing motion.

Tap Float to hold a steady power/speed, or Loop to draw a custom pattern that repeats. Since the toy reacts as you draw, you can feel the pattern in real time instead of creating it blindly and testing it later. If you like what you made, tap Record to save it to My Patterns.

Lovense typically allows separate control of each motor. Unfortunately, the two arms’ separate vibrating motors are tied together. Setting the vibration intensity of the internal arm does the same to the external arm. But the flexing motion is still controlled separately.

For presets, the My Patterns screen includes Lovense’s default patterns, anything you’ve saved, and patterns downloaded from Lovense’s active community library.

Lovense’s sound-reactive mode is also the best I’ve used. You can set a minimum decibel threshold, so the toy stays still until the room gets loud enough, and adjust sensitivity to control how much of the toy’s power range it uses. The live decibel readout makes it easy to calibrate. Many other apps either combine these controls or don’t offer a threshold at all.

The music-sync mode works with Spotify or local files and follows the music well enough for hands-free variation. You can cap the intensity to keep it in your comfortable range.

Lovense also includes a few useful extras: Voice Control, device-to-device control with certain Lovense toys, and per-toy max intensity settings. The intensity cap is helpful if you want to limit noise or prevent a partner from setting the toy too strong.

Overall, the Lovense app’s close-range features are excellent – and the best of any brand I’ve tested.

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.

Lovense also has the best long-distance experience of any brand, by a wide margin.

During messaging or video calls, your partner gets the same excellent Remote screen used for close-range control. They can set a steady intensity or flexing speed with Float or draw a repeating pattern with Loop, so long-distance control doesn’t feel stripped down. The only small downside is that you can’t control your own toy during a video call – only your partner can.

The video call tools are excellent. Incoming calls are easy to notice and accept, and once you’re in a call, the video feed is clear. You can mute, toggle your camera, switch between front and back cameras, cast audio to a speaker, or end the call. The controls stay out of the way until you tap the screen, and you can move your self-view so it doesn’t block your partner.

The app also handles normal phone use well. You can lock your screen or switch to another app without disrupting the session.

Messaging is equally strong. The thread is easy to follow, and you can send voice notes, photos, and videos from your camera or camera roll. There’s also an optional “burn after reading” feature for one-time viewing that prevents screenshots, and it works as intended.

Lovense gives you helpful partner settings too. You can let a trusted partner auto-accept control requests, get a notification when they come online, or hide your online status from specific people. Each partner can have different settings.

Lovense also offers the broadest anonymous and group control options. You can send a one-time control link or create a group link for up to 10 people. When the time runs out, they lose access and can’t request control again.

If long-distance play is the main reason you’re buying a wearable vibrator, Lovense is the best choice.

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 Flexer’s connectivity is excellent. Lovense has the most reliable app connection of any brand I’ve tested, both for nearby Bluetooth control and long-distance play.

Pairing is quick: the very first time you connect, just tap Add Toy, turn the Flexer on, and it appears in the app within seconds. After that first setup, it auto-connects as soon as you turn it on with the app open.

Once paired, the Flexer stays connected through normal phone use, including locking your screen, switching apps, or leaving the app idle.

It also handles body interference very well. Body tissue can weaken Bluetooth more than walls or clothing, which is why some wearable vibrators work fine for solo control but drop connection when a partner controls them from certain angles. In our body-interference test, the Flexer stayed connected through all three positions, including the hardest one.

Bluetooth range was excellent too, reaching about 315 feet in our clear line-of-sight test. That’s one of the longest ranges we’ve measured for a wearable and far more than most people will need. Though walls and other interference will shorten real-world range.

If the it does disconnect, the app reconnects automatically once the signal is clear. A red “Reconnecting…” message also tells the controlling partner that control has paused. You can choose whether the toy stops vibrating during a disconnect with Auto-Stop, or keeps vibrating at the last intensity level until it reconnects.

Long-distance connectivity is also excellent. The toy connects to your phone over Bluetooth, and your phone connects to your partner’s phone over Wi-Fi or cell data. Since the Bluetooth connection is strong, long-distance play works well as long as your internet connection is decent. Sessions stay stable, commands go through reliably, and locking your phone or switching apps doesn’t disrupt control.

One quirk: if you start a session on Wi-Fi and then switch to cell data, the first switch can drop control and require a quick re-invite. After that, switching works normally. To avoid this, start the session on cellular data – then you can switch freely between the two.

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).

The Lovense Flexer 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.

• best wearable vibrators (wearables only).

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 Flexer’s on-toy controls work as a backup, but the app is the main way to use this toy. A single button cycles through three power levels and four patterns on the same loop, with the vibration and motion functions linked together.

Lovense lets you customize the three on-toy preset power levels in the app so the button provides access to the levels you like. This can be useful if you don’t want to mess with the app for quick, immediate interaction.

However, the button sits far enough back on the toy that it’s annoying to reach while using. So the app is really what you should count on in typical use.

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.

The Flexer’s fit is workable when using it hands-free in bed, but it moves around a lot and does not feel secure when walking. Some of that movement is intentional – the flexing arm presses both internally and externally. But it also makes the stimulation feel a bit chaotic and less secure.

The bigger issue is that the Flexer is rigid and not adjustable. If the shape lines up well with your anatomy, it can be very stimulating. If it doesn’t, there’s not much you can do to improve the fit. That makes it a riskier pick than adjustable dual-stim toys like the Lovense Dolce, which stays in place better and has a good adjustable spine to help you get a better fit for your individual anatomy.

The Flexer feels least secure when the flexing motion is on. With vibrations alone, it’s more stable, but still has a “half in” feeling that makes me less confident moving around. During light activity, especially bending or squatting, I worry it could work its way out. And it’s not comfortable to wear when moving around anyway.

I’d treat the Flexer as an in-bed toy, not something for walking around. For dual-stimulation you can wear around more easily, try pairing the Lovense Ferri with the Lovense Lush 4 or Lush Mini.

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.

The Flexer can be an uncomfortable dual-stimulation wearable, and takes some warmup and unique preferences to enjoy. It is rigid, girthy, and the flexing motion can pinch against my pubic bone.

It’s best for those who prefer a fuller internal feel, and don’t mind firm pressure on your clit.

I find it most comfortable lying in bed. Sitting up or bending forward makes it feel too tight. Walking around is worse – my movement feels restricted in normal activities like walking, stairs, standing, or sitting.

This might be fine for those who value the strong, unique stimulation it provides. But if comfort is a priority, the Fantasy For Her G-spot Stimulate-Her is one of my most comfortable dual-stimulation wearables in bed. Or, egg and panty vibrators are more comfortable to wear around.

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 Flexer is very loud. The vibrations are high-pitched and buzzy, and the flex motor adds a distinct non-constant mechanical sound that draws attention.

Decibel readings were 49.7 dBA on low and 54.7 dBA on high. Those numbers are not extreme, but the high-pitched, uneven sound makes it easier to hear.

In our background noise masking test, 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. Even with our loudest background audio playing all the Flexer’s settings were audible – low power was barely noticeable, but middle and high were still unmistakable.

We also check whether my partner can hear me use it behind our closed bedroom door. The middle and high powers were audible. A box fan helped enough that high power was barely audible and probably would not be noticed in normal use. To be completely masked, I had to play music in the bedroom.

If you want dual-stimulation from motion that’s quieter, consider the Lelo Ida Wave.

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 Lovense Flexer has a great battery life, lasting 95 minutes on high in our test. That’s comparable with or better than other dual-stimulation wearables, and plenty for most in-bed or long-distance sessions.

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 Flexer is IPX7 waterproof and easy to clean with soap and water. You can rinse it thoroughly after use, including at the hinge, where the internal and external arms meet.

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 Flexer feels sturdy and well-built. I’ve had mine since 2022 and it’s still working how it did when I first got it.

It is covered in smooth, firm silicone, and the connecting arm between the internal and external sections is very strong. The flexing movement comes from the motor, not from the toy feeling floppy or manually bendable.

That rigidity contributes to the comfort problems, but it also makes the toy feel durable.

My main frustration with the build has to do with noise. The flex motor can be especially high-pitched in a cheap-sounding way. It’s not as quiet as premium options like the Lelo Ida Wave.
