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 Sexy Secret’s vibration power and rumbliness in detail.

Here’s the main conclusion:

The Sexy Secret has one of the weakest, buzziest clit motors of any panty vibrator I’ve tested, so even though it fits on my clit well, the result is more tickly than stimulating.

If hands-free clit stimulation is your priority, go with the Lovense Ferri – same price tier, similarly capable app, and more than three times the Sexy Secret’s top power. Or the VeDO Niki (remote controlled, no app) if you prefer a remote or are on a budget.

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 Sexy Secret has one of the weakest clit motors of any panty vibrator I’ve tested, with a top power of just 2.5 out of 10. The only panty vibrator I’ve tested with a weaker motor is its sister product, the Satisfyer Little Secret. Stronger competitors like the Lovense Ferri, NS Novelties Techno Lucy, and VeDO Niki all deliver more than three times the Sexy Secret’s top power.

I can’t orgasm from this toy hands-free, even when I use the strongest setting and press it firmly into my clit with my hand. Its full power range – from a barely-there 0.5 at the bottom up to that 2.5 at the top – sits entirely below the strength I need to orgasm.

The frustrating part is that the fit is doing its job well. The broad, soft silicone arm contours well to my body and stays in firm contact, so the vibrations actually reach my clit. But what reaches me feels underwhelming – the vibration can feel enjoyable, but more as a warmup and slight tease than anything truly stimulating.

For a panty vibrator with a motor strong enough for hands-free orgasm (for me personally), consider the Lovense Ferri if you want excellent app control. On a budget, the VeDO Niki (remote-only) and the Techno Lucy (app controlled, but more basic than Satifyer’s) both pair similarly great body-contoured shapes with much stronger motors than the Sexy Secret’s.

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 rate panty vibrators with rumbly vibrations higher than buzzy ones because rumbly is what most people prefer – but it’s a personal preference, so consider what you like.

The Sexy Secret is on the buzzy side. Vibrations start neutral at its lowest power (80 Hz) and quickly climb into the extremely buzzy range, hitting 144 Hz at the top. The motor’s median frequency is 127 Hz – well into the extremely buzzy band.

Vibrators always become buzzier as you increase power, so this curve isn’t unusual on its own. But because the motor is so weak (covered above), there’s no point on the curve where the vibrations feel rumbly and impactful: by the time you’ve turned the toy up enough for the vibrations to register, you’re already deep in extremely buzzy territory. That’s why the sensation feels tickly – the buzziness layers on top of the weakness, giving the vibrations a high-frequency, surface-level character rather than the deep, resonant feel rumbly vibrations provide.

Most panty vibrators actually lean buzzy, but plenty have better power so that the vibrations still feel impactful – for instance, the Lovense Ferri is also buzzy, but its strength makes it the one I can orgasm with most easily.

If you specifically prefer rumbly vibrations, the VeDO Niki is a better option. It’s the only panty vibrator I’ve tested centered around the rumbly range (66 Hz at the median) and it has great power too.

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 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 Satisfyer’s app – its close-range features, long-distance experience, and connectivity – in detail.

Here’s the main conclusion:

Satisfyer’s app is the closest second to Lovense’s. Its close-range and long-distance features are genuinely strong, with only minor tradeoffs compared to Lovense. Connectivity is the one mixed area: the app is designed well, so there aren’t bugs causing connection issues in close or long-distance play. But the bluetooth signal struggles when there’s a lot of your body between the phone and the toy, which can happen more often when letting a nearby partner control your toy from certain angles.

If app control is your top priority, go with the Lovense Ferri – the absolute best app and panty vibrator. Otherwise, the Satisfyer Connect app is the closest you’ll get to a Lovense-quality without going Lovense.

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 Satisfyer Connect app’s close-range features are great overall – second only to Lovense’s.

The Live Control screen (which is like Lovense’s main Remote screen) is its best feature. Here I can adjust a constant vibration intensity or draw a custom pattern from the same place. You raise or lower the intensity by swiping up or down on the screen. You can also tap the loop button, draw a pattern, and it will repeat. Many apps split those into separate screens, so the seamless switching is nice. There’s also a Boost button for an instant 30-second burst at high power.

The biggest way Satisfyer Connect differs from Lovense is in user experience. It’s harder to tell your exact strength in Satisfyer’s app, so if your partner is controlling, it’s harder for them to have an exact idea what’s happening. Satisfyer can also take more “swiping” to reach your preferred setting rather than single-taps compared to Lovense.

Satisfyer’s Pattern creation is strong with some small downsides. There are three ways to creat your own pattern. The first is drawing a real-time loop from the Live Control screen. We’ve found that the pattern it loops back often doesn’t match what you drew. It speeds it up or oversimplifies it (for instance, it usually transforms pulses to waves) – but this won’t be too big of an issue for most people.

You can also save your full vibration session as a pattern (up to 15 minutes long), so if you like the build-up you had during a certain sesssion, you can replay it. Lastly, you can use the On-Screen Sketch mode to draw a 5-second waveform with an instant preview before saving. This gives very fine-tuned control, because you’re not drawing it in real-time (unlike Live Control). You can preview the feel and start again if you don’t like it.

Satisfyer’s preset pattern selection and adjustability is fairly good. There are a lot of presets to choose from with a variety of waveforms (waves, pulses, triangular waves, gradual ramping, etc.). And you can adjust the intensity of the pattern by swiping your finger up and down on the screen.

There’s also an active Satisfyer community that creates and shares vibration patterns, and you can save these to your presets list. You can sort by “popular” to see which ones are well liked. You can also see a preview of the waveform so you can easily tell which ones are designed for two motors vs one motor, so you can download the ones that fit your toy. Any patterns you created and saved yourself are available in the Presets library to use again too. You can also use the “Sequences” screen to string together a series of preset patterns to play back-to-back.

It does have a few noticeable weaknesses: There’s too many default preset patterns with many of them being very similar, so it clutters the pattern selection screen and makes it harder to find what you’re looking for. The preset patterns all have a descriptive name and an icon of the waveform so you can tell what it should feel like before selecting it – some match well, but others don’t. So you still have to just try them to see what they feel like.

Satisfyer also has some synced audio features like Remotyca Stories and High Touch Meditation.

They have a large library of erotica audio stories for you to listen to. Throughout the story your toy will be vibrating along – usually on a pattern or a constant setting that’s gentler to moderate power near the beginning of the story. Toward the end of the story, it ramps up to a stronger, constant vibration to help you orgasm. There is a slider so you can adjust the intensity yourself during the story too.

This can be a great feature for people who like erotic audio. But it can be difficult to find stories by your interest because you can’t filter by specific fantasies or tags. There is a search bar, but it doesn’t work very well. So you have to scroll through stories and read their descriptions to know if it interest you.

The meditation feature works the same as the Erotica feature, except that the audios are guided meditations, which can be great for people who enjoy combining masturbation and mindfulness practices.

Music Vibes and Ambient Sound are the weaker of Satisfyer’s features. Music Vibes feels reasonably matched to a song’s softer moments, but once the music gets full, the toy just does a steady vibration with a bit of a wobble, so it’s not very accurate.

Ambient Sound is the sound-reactive mode – the toy vibrates in response to noise around you. It works, but the controls are more limited than the best apps. The best apps like Lovense, give you two separate sliders: one to set how loud a sound has to be before the toy reacts, and one for how intensely the toy vibrates when it does. Satisfyer combines both into a single slider, where sliding up makes the toy respond to quieter sounds and raises the intensity at the same time.

The problem is that usually you want the opposite behavior – you want the toy to vibrate stronger only when the sound around you is louder. So it’s not ideal in Satisfyer’s app.

If you want a better panty vibrator with the absolute best close-range features, go with the Lovense Ferri. But the Satisfyer’s app is the closest second to Lovense’s – it’s just a bummer the Sexy Secret itself is not stimulating enough.

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 Satisfyer Connect app’s long-distance experience is good too – again the closest second to Lovense’s.

During a long-distance session, your partner uses the same Live Control screen they’d use during nearby Bluetooth play. They get the same intensity adjustment controls, the same Loop function for drawing real-time patterns, and the same waveform display so they can see what you’re feeling. The one slight reduction from close-range is that there’s no prompt to save patterns at the end of a long-distance session like there is during close-range play.

You can share control of your toy with or without video and voice.

Getting into a call is easy. There’s a clear accept/reject popup, all the standard controls are there (mute, camera toggle, switch front/rear, end), and locking the phone or backgrounding the app doesn’t drop the connection – the camera freezes but the toy keeps vibrating, and everything resumes smoothly when I unlock my phone again.

The main downside is what the screen looks like during the call. The vibration waveform always sits prominently across the video feed of your partner and can’t be minimized. The app paints a light blue or pink gradient over the feed to indicate the toy’s power, which is distracting if you want to actually see your partner clearly. Lovense handles the same controls more gracefully – minimizable, no color-tint – so for couples where visual clarity matters, Satisfyer’s video feed is a real downgrade.

Messaging during a session works well (easy back-and-forth, partner gets notified), but the media tools are limited: photos only, no video clips, no voice recordings, and no screenshot-disable for privacy. Lovense’s app does all three.

Satisfyer is also missing a few of the partner-side controls Lovense has: no max-intensity cap, and no setting to control what the toy does on a Bluetooth disconnect (Lovense lets you pick between stopping for discretion or keeping the vibrations going for smoother continuity). There’s no anonymous control or social matching either – niche for most couples.

If long-distance play with the cleanest video and richest partner tools is your priority, the Lovense Ferri is a better option.

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 Sexy Secret’s app connectivity is reliable for everyday solo use and for long-distance play. But the signal can be unreliable under a lot of body interference like often happens when letting a nearby partner control your toy. If outstanding connectivity is important, consider the Lovense Ferri instead.

Pairing the Sexy Secret is typically quick and easy. The very first time takes a couple of seconds (hold the toy’s button until it vibrates twice, then select it from the toys list when it shows up). After that, the app auto-connects when you turn the toy on – which works reliably as long as your phone was the last one connected to it.

If it doesn’t (auto-connect usually only fails after I’ve used a different phone with the toy in between) you typically have to hold the toy’s button for about 10 seconds until you feel several quick pulses to reset it, then re-pair. If that still fails, you may have to “forget device” in your phone’s Bluetooth settings and try again. Tedious, but it gets you back in every time and is typically only necessary if you connect multiple different phones to the toy.

If the connection drops mid-session, reconnection is automatic when the signal returns cleanly. However, when signal is only partially blocked rather than fully gone (say I shift my body and the connection degrades without dropping outright) the app can freeze instead of auto-reconnecting. The fix is to force-close the app and reopen; the toy is typically already paired by the time it loads back up, so control resumes right away. (Avoid tapping “Connect Now” in the disconnect popup – that routes you into a manual screen you’ll need to exit.) Once you know the move it’s not too disruptive, but is still annoying.

Commands go through reliably when I’m controlling my own toy. And the Sexy Secret can handle light to moderate body interference like happens when a partner is controlling your toy while facing you or at a slight angle. But it drops connection when body interference is more substantial.

Water-rich materials like body tissue can significantly dampen bluetooth signals – moreso than clothes or typical walls. Our body-interference test simulates this at three progressively harder positions: the Sexy Secret holds a stable connection at the first two but loses it at the third, most severe angle.

Its sister product, the Satisfyer Little Secret and their egg vibrator (the Satisfyer Petal), all struggle under some body interference so this looks like a Satisfyer-hardware pattern rather than a Sexy Secret-specific defect. The Lovense Ferri holds a stable connection at all three positions, which is important if a partner will be controlling your toy from another room or with a lot of your body in the way.

Bluetooth range comes in around 135 feet in our open-air test (measured with a clear line-of-sight). That’s plenty for partner control across a normal house, but keep in mind that body interference at certain angles will make your real distance shorter.

The long-distance connection is great.

Session start is fast and reliable. There’s a clear Remote Play tab where you send your partner a control or video request; the request shows up wherever they are in the app, and pushes a notification if their phone is locked (you can turn notifications off if you don’t want them).

Sessions don’t drop unexpectedly, commands consistently go through, and the app handles real-world phone behavior gracefully – locking my phone, switching to another app, or backgrounding Satisfyer Connect doesn’t disrupt the session. The app handles switching between Wi-Fi and cell data mid-call smoothly too.

The connection works in two parts: the toy talks to your phone over Bluetooth (the same as during nearby play), and your phone talks to your partner’s phone over Wi-Fi or cell data. Since during a long-distance call, your phone right by you is the one connected to your toy’s bluetooth, the body interference issue doesn’t really come into play. So as long as your cell data or Wi-Fi is decent, the long-distance connection works well.

If a reliable connection through any situation matters most, the Lovense Ferri is a better option – more robust through body interference and a slightly longer Bluetooth range. For solo control, partnered control from angles without much of your body in the way, and long-distance play, the Sexy Secret’s connectivity holds up well.

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 Satisfyer Sexy Secret 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 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.

Since you’ll use the app, the on-toy controls are very basic – a single button cycles through three power levels and seven vibration patterns, with the full power range only available in the Satisfyer Connect app. Three power levels keep the cycle short enough to tap through quickly, though I wish patterns weren’t on the same cycle – most people don’t use them, and it makes it take more clicks to cycle through power levels.

The button itself is easy to feel without looking. It sits center-placed on the broad, plush body – pressing the button pushes the toy into me a bit, but the pressure spreads evenly enough that it doesn’t dig in.

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 Satisfyer Sexy Secret fits extremely securely in bed, but the contact with my clit loosens a bit when I’m moving around.

The magnet that secures it to your underwear is excellent – strong, broad, and covering a generous portion of the back of the toy, it locks the panty vibrator to my underwear very well. The larger magnet prevents the toy from swiveling side-to-side like toys with smaller magnets often do.

In bed, the Sexy Secret stays exactly where I put it. The broad, soft silicone design follows the curve of my body, keeping it in great contact without shifting around, even as the underwear shifts.

While walking or doing anything upright, the toy’s position in my underwear stays in place, but the toy’s pressure against my body loosens. The magnetic anchor keeps it locked to the underwear reliably – it doesn’t drift to the side or come loose – but gravity pulls the underwear (and the toy with it) a bit away from my clit, so the already-gentle vibrations feel even more tickly than they do when I’m sitting or lying down. Sitting back down restores close contact immediately.

This pulls-away-from-the-body dynamic affects most magnetic panty vibrators to some degree, but it’s more noticeable on the Sexy Secret than on most other panty vibrators I’ve tested. If active-wear is a big priority, the Lovense Ferri and NS Novelties Techno Lucy each fit more securely, and are much more stimulating.

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 Satisfyer Sexy Secret is very comfortable.

It’s among the most comfortable panty vibrators I’ve tested in bed. The broad, soft silicone arm sits flush against my clit, the contoured back piece curves easily between my legs, and the whole form is plush and flexible enough that it feels like it melds to my body – no pinching, no awkward pressure points. The broad part by your clit spreads its weight across the area rather than digging in at one spot, and the form flexes with me as I shift around.

It’s also very comfortable when walking and moving around for many of the same reasons. The only complaint is that when I’m walking or doing anything upright, gravity makes the toy apply less pressure on my clit. So the vibrations are more tickly – it doesn’t bother me personally when walking around, but it could bother those senstive to buzzy, tickly vibrations.

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 Satisfyer Sexy Secret is one of the quietest wearables I’ve tested. But it’s only so quiet because it’s weak – for a stronger, quiet panty vibe consider the VeDO Niki.

The Sexy Secret’s decibel readings on low and high power were extremely quiet, too quiet for our Sound Level Meter to pick up on. The ambient room noise was 35 dBA, and the the vibrations never measured higher than this.

It’s also in the most-discreet group of wearables in our Background Noise Masking subtest. In this part of our noise test, my partner listens from three feet away as I wear the vibrator and we play pink noise through a speaker at set volumes. He couldn’t hear the Sexy Secret at any vibration strength under any of our three tested volumes of background noise (56, 62, or 68 dBA).

While its one of the quietest vibrators, it’s also worth noting that every wearable I’ve tested, including the Sexy Secret, is audible in a fully silent room (no pink noise playing) – no matter how gentle and quiet its vibrations are.

The Sexy Secret was also inaudible behind a closed bedroom door. For this part of the test, my partner listens directly outside our bedroom door while I use the toy in bed. For this test, I use it like a handheld toy since wearing dampens sound, and some people want the flexibility to safely re-position the toy or move it around. Holding the toy instead of wearing it gives us the most conservative results. And he couldn’t hear the Sexy Secret at any setting in a silent house, with no fan or music needed to mask the noise.

However, the VeDO Niki is similarly quiet but is also one of the most stimulating panty vibrators I’ve tested, so it’s a better option if you care about power and noise.

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.

In our test, the Sexy Secret lasted 167 minutes continuously running at its highest power. While that’s among the longest battery lives of any panty vibrator I’ve tested, it’s not very impressive because the top setting is very weak so it doens’t use that much battery.

The Lovense Ferri had basically the same runtime in our test (168 minutes) while being the strongest panty vibe we’ve tested (3.7x stronger than the Sexy Secret).

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 Sexy Secret is fully waterproof (IPX7) so it’s very easy to clean. You can run it under a faucet or submerge the whole toy while scrubbing it with soap and water.

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 Sexy Secret is well-built. Soft silicone coats the entire toy, the magnet holds firmly to the underwear, and the on-toy button is responsive with a noticeable click. The whole form of the toy is flexible and plush for a high-quality feel – it’s just that the motor’s too weak.
