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.

In the next sections, I’ll cover the Niki’s vibration power and rumbliness in-depth.

Here’s the main conclusion:

The Niki is one of the most stimulating panty vibrators and one of the few I can orgasm with hands-free. It’s strong, transfers the vibes where they should go, and is the most rumbly panty vibe I’ve tested. If you value raw power most, go with the stronger Lovense Ferri. If strong, rumbly vibrations matter more, go with the Niki.

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.

The Niki’s clit motor hits a top power of 8.0 out of 10 – great power, but not the strongest panty vibrator out there. Both the Lovense Ferri and NS Novelties Techno Lucy are stronger on high power, though both are also noticeably buzzier than the Niki. Where the Niki stands out isn’t raw power, though – it’s that the broad, flexible, curved design delivers that power to your body unusually well – essential for good stimulation in a hands-free toy. Among panty vibrators, only the Ferri transfers more of its motor’s strength to the clit.

For me, the Niki’s 8.0 top strength is enough power to orgasm hands-free. If top vibration strength is your main priority, go with the Ferri – but the Niki is plenty powerful for most people.

The Niki has six power levels spanning a wide range, from a very gentle 1.0 for warmup up to 8.0 at the top. That low end matters more with a wearable than with a handheld because you can’t just lift a panty vibrator off your body when things start feeling too intense – it’s nice to be able to dial down without reaching to pull the toy out of place.

Vibration transfer is where the Niki really stands out from most panty vibes. With a handheld you can position the vibrator exactly where you want it and just press harder to make the vibes feel more intense; with most wearables, you can’t, so the toy’s shape has to naturally transfer the vibrations where they should go. And the Niki’s shape does that well – its broad, flexible, curved design stays consistently in contact with my body transferring the vibrations right to my clit.

I wear it two different ways: with the top near my clit and the back end toward my vagina, or my preferred “upside-down” way with the top just under my clit and the rest of the toy wrapped up around my pubic bone. The vibrations transfer really well either way, but the toy stays even tighter to my body with the upside-down method.

The Niki’s curve also lets you press harder when you want to for more stimulation – something flat panty vibes can’t do. When you’re sitting, you can shift your weight against the end of the toy that’s opposite your clit. The surface pushes against the base and the curve tilts the clit end to press more firmly into you making the vibes feel stronger. It’s the closest a hands-free wearable gets to the better pressure control of a handheld.

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.

We rate rumbly vibrations higher than buzzy ones because most people prefer rumbly. But it’s a personal preference, and some people like buzzy vibrations more.

The Niki is the most rumbly panty vibrator we’ve tested. Every other panty vibrator I’ve tested – the Lovense Ferri, We-Vibe Moxie+, NS Novelties Techno Lucy, and Romp Party – center around around the moderately or extremely buzzy frequency range. The Niki is the only one with a primarily rumbly clit motor.

The Niki’s lowest settings are extremely rumbly, the middle settings stay moderately rumbly, and only the very top setting feels neutral – never becoming buzzy. All the other panty vibrators we’ve tested become buzzy on their top settings. The Niki’s rumbliness has real power behind it too – the motor is strong as well as deep.

If rumbliness is what you want from a panty vibrator, the Niki is the best choice – no other panty vibrator I’ve tested comes close. If you care more about raw power than rumbliness, the Ferri is excellent – it’s less rumbly, but it’s stronger with excellent vibration transfer, and I can orgasm hands-free from it just as easily as from the Niki.

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.

Like all panty vibrators, the VeDo Niki 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 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 VeDo Niki isn’t controlled through an app. App control lets you create custom patterns, control multiple motors or toys, play long-distance, and lets a controlling partner see exactly what your toy is doing. If that matters to you, see our app-controlled recommendations in these guides:

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

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 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 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.

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.

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

Here’s the main conclusion:

The Niki has one of the better panty-vibe remotes – reliable connection, quick response, and fast, direct power buttons. Its main limitations are typical of remotes versus apps: less partner feedback and shorter range. Go with the Lovense Ferri for app control, but the Niki has great remote control, which can be nice if you don’t want you or a partner to be tied to a phone.

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 Niki’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 – you can move forward and backward through the six power levels with dedicated + and – buttons. Pattern navigation uses a single-button cycle loop – clicking forward through the nine patterns one at a time, with no way to go backward to a previous pattern. In practice this doesn’t matter that much, since most people stay on steady vibrations rather than cycling through patterns. You can also adjust the intensity of each pattern.

The remote is comfortable to hold, but the buttons themselves are less tactile than the best panty-vibe remotes – they’re not raised enough to tell which is which by feel, so I have to look at the remote to find the right button – something you get used to as you use the remote more.

Like most remotes, the Niki’s gives your partner just a faint blink when you press a button – no way to tell what setting your toy is on. That’s fine if you’re using the Niki yourself and many partners won’t mind. Others find it less engaging when they can’t tell what your toy is doing and what you’re actually feeling. An app-controlled panty vibe gives your partner real-time visuals of the toy’s vibrations, which makes controlling it feel more engaging. If that’s a priority for you, the Lovense Ferri is the best app-controlled panty vibe, and Lovense has the best app of any brand.

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.

The Niki’s remote connectivity is excellent, though its maximum range lands in the middle of the pack.

Body tissue between a remote and toy is typically the main thing that breaks a remote’s signal during partner control, but the Niki holds up well to this.

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

The remote reaches about 60 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 this gives you enough flexibility for most activities, and especially any same-room use. If you need an especially long range, many app-controlled toys stay connected farther – for instance, the Lovense Ferri stayed connected until 190 feet in our same test.

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.

Like most wearable vibrators the Niki’s on-toy controls are limited by design, since you’ll typically use the remote to control it. There’s a single button that cycles through a steady vibration and nine patterns – all at one fixed intensity. To use the toy’s full six-level power range, you need the remote.

The button itself has a subtle feel and sits further back on the toy, so it takes some reaching to press if for some reason you want to change settings without the remote. When you do press the button, the toy’s broad, flexible shape keeps the pressure comfortable against your body. The on-toy button works as a backup, but the remote is the main way you’ll use the Niki.

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.

In my experience the Niki stays securely in the ideal place when wearing it in bed and during normal everyday activity like walking or going up and down stairs – but it shifts more during heavy movement like running or jumping.

The Niki’s broad, flexible, curved design contours to your body, so it stays snug and doesn’t shift during light activity the way some slimmer or straight panty vibrators can. It’s also secured to your underwear by a magnet – essential for any panty vibrator to fit securely. The Niki’s magnet is on the weaker side compared to other panty vibrators, but in normal wear that’s not really an issue – the form-fitting shape prevents the kind of shifting, tilting, or movement that would pull the magnet off, and the magnet itself is slim and form-fitted to the toy so it doesn’t get bumped off easily. The magnet can come loose when you actively re-position the toy in your underwear, but otherwise has stayed attached for me.

Heavy activity is not as good. When running, the toy bounces on landings and the stimulation briefly pulls away before gravity returns it. With jumping jacks, it slid further down in my underwear, and I had to adjust the placement afterward. It never fell out, but during vigorous movement the form-fitting shape can’t fully prevent the toy from shifting, and the relatively weak magnet doesn’t pick up the slack the way a stronger one can.

If you specifically want a panty vibrator that holds securely under intense movement, the NS Novelties Techno Lucy holds up better. Otherwise, the Niki’s fit is reliable for the way most people will actually use it.

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 Niki is one of the most comfortable panty vibrators I’ve tested, and the comfort holds up just as well when I’m moving around as it does lying in bed.

That’s less common than you’d expect. Most panty vibrators are noticeably less comfortable during light activity than lying down – mostly because toys can poke or apply uneven pressure when walking – but not for the Niki. The Niki’s broad, flexible, curved shape distributes pressure evenly across my body, so there’s no digging in, no pinching when I close my legs, and no uncomfortable tapping when I move. It blankets the area rather than pressing into a single spot.

One wear note: I find the Niki most comfortable when worn upside-down (so the charging port end is facing upward), with the toy’s curve wrapping up around my pubic bone. The reverse orientation is still great, but “upsidown” is slightly more comfortable and stimulating for me.

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 VeDO Niki is a very quiet panty vibrator – one of the areas it outperforms the Lovense Ferri a bit. Decibel readings on both low and high power were too quiet for our Sound Level Meter to pick up on – the ambient room noise was 35 dBA, and the Niki never measured higher than this.

It’s in the most discreet group of wearables I’ve tested for our Background Noise Masking 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). My partner couldn’t hear the Niki at any vibration strength under any of our three tested volumes of background noise. It is definitely audible in our room without any background audio playing – but every wearable vibrator I’ve tested is audible in a fully silent room, no matter how gentle and quiet its vibrations are.

For our closed-bedroom-door test, my partner stands directly outside the bedroom 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 re-position the toy or move it around – holding it instead of wearing it gives us the most conservative results. My partner couldn’t hear the Niki on its low or middle power levels. He could just barely hear it on high in our completely silent house – pretty faint, and easily masked by cars passing by outside. When I re-checked while actually wearing the Niki, the sound was significantly dampened and he couldn’t hear it on any setting.

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 Niki has a short battery life. It lasted 55 minutes continuously running at its highest power during our test – below the higher-end panty vibrators. Since you’ll use the Niki’s lower power levels too, your real-use runtime will likely be longer.

If long battery life is a priority, go with the Lovense Ferri – it lasted 168 minutes during our test, about three times the Niki’s runtime.

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.

Cleaning the Niki is straightforward in practice, but our rating is conservative because we couldn’t confirm the toy’s exact waterproof status. VeDO lists it as “splashproof – suitable for shower” on their site, which usually corresponds to an IPX5 or IPX6 rating. Products with those ratings are safe to clean under a running faucet or use in the shower, but IPX4 products (which are also sometimes called “splashproof”) are not. We emailed VeDO to confirm the exact IPX rating and didn’t hear back, so we rated the Niki’s cleaning based on not being able to run it under a faucet.

In practice I do run most of the Niki under a faucet without being especially careful, just keeping water away from the charging port and wiping that area with a cloth. I haven’t encountered any issues.

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.

The Niki feels well-built. It’s coated in smooth silicone with a small plastic section around the charging port, and the toy’s slight flex feels sturdy and adds to its comfort. I’ve had mine since 2021 and it’s continued to operate as expected. The plastic remote is very lightweight and cheap-feeling, but it functions well.
