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 Little Secret’s vibration power and rumbliness in detail.

Here’s the main conclusion:

The Little Secret has the weakest clit motor of any panty vibrator I’ve tested, so I don’t find it stimulating at all.

If hands-free clit stimulation is your priority, go with the Lovense Ferri – same price, and roughly ten times the Little Secret’s top power. Or the VeDO Niki (remote-only) if you’re on a budget or you really prioritize rumbliness.

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 Little Secret has the weakest clit motor of any panty vibrator I’ve tested, with a top power of just 0.80 out of 10. Even its sibling Satisfyer Sexy Secret – which is also too weak – hits more than three times that strength at the top.

The panty vibrators I can actually orgasm with hands-free, like the Lovense Ferri, NS Novelties Techno Lucy, and VeDO Niki, all reach roughly ten times the Little Secret’s top power.

The vibrations aren’t even stimulating if I use it like a handheld toy and press it into me. Its full power range – from a barely-there 0.50 at the bottom up to that 0.80 at the top – is so narrow that the motor barely changes between its lowest and highest settings.

The fit does its job well enough, at least in bed. The broad, plush silicone arm contours well to my body and stays in firm contact, so what little strength the motor produces reaches my clit. But what reaches me feels tickly – more like a slight tease than anything stimulating.

Consider the Lovense Ferri or VeDO Niki (remote-controlled) for stronger vibrations.

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.

The Little Secret is very buzzy. Its median frequency is moderately buzzy at 101 Hz, and it climbs to an extremely buzzy 122 Hz on high. The buzziness combined with low power makes them feel tickly and surface level.

Most panty vibrators actually lean buzzy, but many have enough power to 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 in 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.

Like all panty vibrators, the Satisfyer Little Secret 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 the Little Secret’s app features and its connectivity in detail.

Here’s the main conclusion:

Satisfyer Connect is the closest second to Lovense’s app with minor tradoffs. Connectivity is reliable for solo use and great for long-distance. But the bluetooth signal struggles when there’s a lot of your body between the phone and the toy. This happens more often when letting a nearby partner control your toy from certain angles.

Unfortunately, the low power negates the benefits of the app. It’s actually less expensive to go with the Lovense Ferri – the absolute best app and panty vibrator I’ve tested.

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 has great close-range features – second only to Lovense’s. The Little Secret uses the same app as the Satisfyer Sexy Secret, so the close-range experience is identical.

The best feature is Live Control, which lets you control steady vibration or draw a custom pattern from the same screen. Swipe up or down to adjust intensity, or draw a looped pattern that repeats. There’s also a Boost button for a 30-second burst at high power.

The main downside is precision. Compared to Lovense, Satisfyer makes it harder to see the exact strength level, so partner control feels less clear. It also takes more swiping to reach your preferred intensity.

Satisfyer’s pattern creation tools are strong. You can draw a real-time loop, save a full vibration session as a reusable pattern, or use On-Screen Sketch to draw and preview a 5-second waveform before saving. The real-time loop tool sometimes simplifies what you draw, but the Sketch mode gives much better control.

The preset pattern library is also solid. There are lots of built-in patterns, community-shared patterns, waveform previews, and a Sequences feature that lets you play several patterns back-to-back. However, the library feels cluttered because many default patterns are similar, and the icons don’t always match how the pattern actually feels.

Satisfyer also includes synced audio features like Remotyca Stories and High Touch Meditation. Remotyca Stories pairs erotic audio with vibration patterns that usually start gentler and ramp up toward the end. It’s a fun feature if you like erotic audio, but browsing is frustrating because you can’t filter by specific fantasies or tags, and the search tool is weak. High Touch Meditation works similarly, but with guided meditations instead of erotica.

The weaker features are Music Vibes and Ambient Sound. Music Vibes responds okay during softer parts of a song, but fuller music usually turns into a mostly steady vibration. Ambient Sound reacts to noise around you, but the controls are too limited: Satisfyer combines sound sensitivity and vibration intensity into one slider, instead of separating them like Lovense does.

Overall, Satisfyer Connect is the closest app to Lovense for close-range control. But if you want the best panty vibrator with the strongest app features, the Lovense Ferri is still the better choice – especially because the Little 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. As with close-range, the Little Secret runs on the same Satisfyer Connect app as the Satisfyer Sexy Secret, so the long-distance experience is the same.

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, Loop function for drawing real-time patterns, and 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 app paints a light blue or pink gradient over the feed to indicate the toy’s power, which is distracting if you want to see your partner clearly, and can’t be removed. 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, or 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.

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 Little Secret’s app connectivity is reliable for solo, and 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 Little 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 Little 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 Little Secret holds a stable connection at the first two but loses it at the third, most severe angle.

Its sister product, the Satisfyer Sexy 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 Little 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 came in around 145 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. For solo control, partnered control from angles without much of your body in the way, and long-distance play, the Little 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).

In the next sections, I’ll cover the Little Secret’s remote features and connectivity.

Here’s the main conclusion:

The Little Secret’s remote is easy to use, with a reliable connection. But the toy’s motor is simply too weak for that to matter.

If you want a great remote-controlled panty vibrator with stimulation worth controlling, go with the VeDO Niki.

The Little Secret’s remote is great, with a few minor downsides – most of which are typical of remotes compared to apps.

Power control is fast and direct – dedicated + and − buttons let you move forward and backward through three power levels separate from patterns so you’re never stuck cycling through a ton of settings to step the intensity back down.

The 7 patterns are on a separate single-button cycle loop, and you can adjust the intensity of each of them.

The remote’s comfort is just decent. It’s a thin, flat rectangle, so it doesn’t sit in my hand as nicely as some remotes, but it’s not uncomfortable. Unfortunately, the buttons aren’t easy to use without looking. They’re flat, hard to feel, and you can hardly feel the click, with an unintuitive button layout. You’ll likely need to look at the remote while using.

Like most remotes, partner feedback is limited. The Little Secret gives your partner just a faint blink when they press a button – no indicator of what setting the toy is on, or even whether the toy is currently running (the light blinks the same way whether the toy is on or off).

That’s fine if you’re using the remote yourself, and many partners won’t mind. But if you want a partner to actually know what your toy is doing while controlling it, apps are better than remotes in that way.

The Little Secret’s remote connectivity is excellent, with less issues from body interference compare to the app.

Body tissue between the remote and the toy is the main thing that often breaks a remote’s signal during partner control – your body sits in the signal path between your partner’s remote and the toy.

Our body-interference test simulates this scenario at three progressively challenging angles, and the Little Secret holds a stable connection through all of them – meaningfully more reliable than the Satisfyer Connect app on the same scenario, which drops the connection at the most severe angle. Our test also runs harsher than typical real-world conditions, so partner-controlled play through the remote should stay reliable in practice.

Button presses register with barely any delay – the toy reacts the moment my finger leaves the button, keeping the rhythm of play intact. And there’s no reconnection routine required when starting to play; the remote is always connected.

The remote reaches about 50 feet in our open-air range test – measured with clear line-of-sight and no body interference. This is middle-of-the-road for the wearable vibrators’ remotes we tested, and real-world range will likely be shorter once objects and body interference come in. But the Little Secret has comfortable headroom for most activities, and especially any same-room use.

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.

Like most panty vibrators, the Little Secret’s on-toy controls are limited. The toy sits inside your underwear during use, so you’ll typically use the app or remote.

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 you have to cycle through all seven patterns to get back to a lower power level.

The button is large and easy to feel without looking. The placement is a little different compared to the Sexy Secret, but the plush surface distributes the pressuren evenly, so clicking it while wearing is reasonably comfortable.

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 Little Secret fits very securely in bed, but the contact with my clit loosens when I’m moving around.

The magnet that anchors the toy to your underwear is decent strength and holds well through fabric. However, it’s not as secure as the Sexy Secret’s larger, more flush magnet. I find the Little Secret’s magnet easier to accidentally knock off compared to the Sexy Secret.

In bed, the Little Secret stays exactly where I put it. The broad, plush silicone arm curves with my body, and the contoured design prevents it from shifting around much, even when my underwear shifts.

While walking or doing anything upright, the toy stays firmly clipped to my underwear, but its pressure against my body loosens. 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.

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 Little Secret is among the most comfortable panty vibrators I’ve tested – outstanding in bed or when actively moving around.

In bed, the Little Secret essentially melds to my body. The broad clitoral section blankets the area very comfortably. The contoured lower region tucks easily between my legs – it’s the kind of toy I can forget I’m wearing.

While walking or doing anything upright, the form itself stays exceptionally comfortable. The only complaint is that gravity pulls the toy a bit farther from my clit, so the already-gentle vibrations feel even more tickly than they do in bed, and some people may find that tickling sensation uncomfortable.

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 Little Secret is one of the quietest panty vibrators I’ve tested – but only because it’s so weak. For a similarly quiet panty vibrator with much stronger stimulation, go with the NS Novelties Techno Lucy (app-controlled) or VeDO Niki (remote-controlled).

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

The Little Secret is also in the most-discreet group of wearables 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 Little Secret at any vibration strength under any of the three background-noise levels. It’s audible in our room without any pink noise playing – but every wearable I’ve tested is, no matter how gentle and quiet its vibrations are.

For the closed-bedroom-door part of the test, my partner listens directly outside our bedroom while I use the toy in bed. I use it like a handheld toy here, since wearing dampens sound and some people want the flexibility to safely re-position the toy or move it around – holding it instead of wearing it gives us the most conservative results. He couldn’t hear the Little Secret on any setting from behind the closed door, with no fan or music needed.

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 Little Secret lasted 167 minutes continuously running at its highest power. That’s among the longest battery lives of any panty vibrator I’ve tested – but it’s only because the motor is too weak to draw much power.

The Lovense Ferri had basically the same runtime in our test (168 minutes) while reaching roughly ten times the Little Secret’s top power.

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 Little 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 Little Secret feels well-built, with one caveat: the magnet protrudes a bit from the back of the toy with a shape that’s easy to accidentally knock off. Its sibling Satisfyer Sexy Secret doesn’t share that vulnerability – its magnet sits at the front of the toy with a wider, more securely-shaped hold.

The weak, tickly vibrations can also feel low quality. But otherwise, the Little Secret seems well-made – soft silicone coats the entire toy. The on-toy button is responsive with a noticeable click, and the whole form is flexible and plush.
