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

Here’s the main conclusion:

The Ferri is the most stimulating panty vibrator we’ve tested, and one I orgasm with hands-free the easiest.

It’s the strongest panty vibe I’ve tested and transfers more of its motor’s power to your clit than any other. Like most panty vibrators, the vibrations are buzzy rather than rumbly. If rumbly stimulation matters more to you, go with the VeDO Niki. If power matters more, go with the Ferri.

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 Lovense Ferri reaches a top power of 9.35 out of 10 – the strongest of any panty vibrator we’ve tested, and it’s the one I orgasm with the easiest.

Other panty vibrators I recommend like the VeDO Niki and the NS Novelties Techno Lucy top out at 8.0 and 9.0. And the range available through the app is wide, from a very gentle 1.0 up to that 9.35, so there’s soft warmup levels and strong upper levels.

The Ferri also transfers that power to my clit better than any other panty vibrator I’ve tested. With a handheld toy you can position the toy where you want it and press harder for more intensity; but with wearables the toy’s shape and fit have to do all the work of delivering the motor’s strength to your body. The Ferri is one of the few panty vibrators that does an excellent job transferring vibrations to my clit. The slightly curved design hugs the body, and the short length prevents the toy from pivoting or getting knocked out of place with movement.

And the Ferri’s curve with a taller front also lets you apply more pressure when you want to without using your hands – something flat panty vibes can’t do. When you’re sitting, shifting your weight against the end opposite your clit tilts the toy and presses the clit-end more firmly into you, making the vibrations feel stronger. It’s the closest a hands-free wearable gets to the pressure control of a handheld.

The stimulation profile here is focused and precise rather than broad and blanketing. If you prefer broad stimulation that spreads the stimulation out, the VeDO Niki is also a good option, but not quite as strong.

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 most people prefer them, but it’s a preference and some people enjoy buzzy vibrations more (I like them personally).

Like most panty vibrators, the Lovense Ferri’s rumbliness is mediocre. The Ferri’s vibrations are moderately buzzy at medium strength, and extremely buzzy at the top of its range. Although its lowest settings are rumbly, most people will use them mainly while warming up. Vibrations always become buzzier as you increase power, and by the time you reach the upper levels that you’ll likely need to orgasm, the vibrations are entirely in the buzzy range.

This buzzier feel is typical of most panty vibrators, including the We-Vibe Moxie+, NS Novelties Techno Lucy, Romp Party and others. The small motors that fit inside a panty vibe tend to need to spin faster (be buzzier) to produce the power larger motors can at slower (more rumbly) speeds.

If rumbly vibrations are a strong preference for you, the VeDO Niki has much deeper-feeling vibrations. I personally enjoy both the buzzy feel of the Ferri’s vibrations and the rumbliness of the Niki’s.

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 Lovense Ferri 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 – that’s why I personally enjoy it more than the Lovense Lush 4 and Lush Mini. 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 Sexy 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 Lovense Remote app’s close-range and long-distance features in depth, plus the Ferri’s connectivity in both modes.

Here’s the main conclusion: Lovense’s app is the best of any brand’s I’ve tested, by a wide margin.

I have many remote and app-controlled toys, and Lovense’s app provides the most control, is easiest to use, and has the most reliable connectivity.

If app control matters a lot to you in a panty vibrator, the Ferri is the best choice.

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 Ferri’s app has the best close-range features of any panty vibrator I’ve tested.

From the main remote screen, you’ll control the Ferri by dragging its control dot up and down to adjust the power. Tap “Float” to keep the power constant or click “Loop” to quickly repeat a pattern you draw on-screen. This makes it easy to set your Ferri exactly to your preferred intensity or quickly create your own vibration patterns from the same screen.

The vibrations play as you draw, so you can feel whether you actually like the pattern – some apps make you draw a waveform blindly, save it, then play it back to feel what it does. Tapping “Record” also saves the pattern to “My Patterns” for re-use if you enjoyed it.

You can also connect and control multiple Lovense toys at once with each motor getting its own dot on the Remote screen. So if you have both a Lovense Lush 4 and a Ferri, you can control them together for simultaneous clit and G-spot stimulation (which I personally prefer over using the dual-stimulation Lovense Dolce). Or you can control your own toy and a nearby partner’s toy at once. We tested four toys simultaneously without issue.

For preset patterns, you can use the “My Patterns” screen which has four defaults to choose from, plus anything you’ve drawn and saved, and any patterns you’ve downloaded from Lovense’s community library. Lovense has an active community creating and sharing patterns to browse and download.

Sound-reactive control is also excellent and the most practical I’ve used in any app. You set a minimum decibel threshold – the toy stays silent when the sound around you is below the threshold. And you set a sensitivity – how much of the toy’s power range will be used when the sound is above the threshold. There’s also a live decibel readout to calibrate against the room you’re in. Many other apps try to combine these settings or don’t even have a threshold control.

The music-sync mode is pretty good: it follows what’s playing on Spotify or your local files, but the only real control is capping the maximum intensity. It works fine as a way to get changing vibrations without having to control anything yourself.

Lovense has a few niche extra control features and settings that can be helpful – Voice Control if your fingers are otherwise occupied, and Device-to-Device control where another Lovense toy (the Max 2, Nora, or Solace) drives the Ferri’s vibrations through the controller’s own movements. You can also set a max-intensity setting for each toy to cap how high the vibrations can go – this can be useful both for keeping the toy below a noise threshold and for limiting how high a partner can push it if you’re sensitive to overstimulation.

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

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.

Lovense’s long-distance experience is also the best of any panty vibrator I’ve tested, by a wide margin.

When messaging or video calling, my partner gets the same great Remote screen with the Float and Loop controls, so they can set a constant intensity or draw a looping pattern easily. The long-distance core controls aren’t stripped down like many apps do. One minor downside is that you can’t control your own toy during a video call; only your partner can. Most of the time that’s fine, but occasionally I’d like to take over for a moment to set my own intensity.

The video call tools are excellent and make for a seamless experience with your partner.

Getting into a call is easy – when your partner sends a video call request, there’s a clear screen on your phone with a green accept button or red reject button. Some apps send the request to a particular screen and your partner has to go there to find it, which makes calls easy to miss, but requests in Lovense’s app are noticeable.

When you’re in a video call, you can mute, toggle your camera off/on, flip video to front or back, cast the audio to a speaker, or end the call.

It’s easy to see your partner and access the controls – the video feed is clear by default. Just tap the screen to bring up the control panel. You can also reposition your self-view anywhere on the screen to see your partner more clearly. Some apps keep annoying controls permanently covering the view of your partner.

You can both lock your phone screen or use other apps without issue. The in-app messaging is alo excellent and very easy to use with a thread that’s easy to follow – it looks just like any other message thread. You can send all the important media types you might want to: voice notes, photos, and videos from your camera or camera roll. And there’s an effective, optional “burn after reading” feature for single-time viewing and preventing screenshots.

You can adjust your partner’s settings to auto-accept their control requests so they can take control of your toy by surprise, get a push notification when they come online, or hide your online status from them specifically. And each partner’s controls can be set differently.

Anonymous and group play is broader than any other app-controlled brand. You can send a one-time control link to someone or create a group link for up to 10 people to control your toy. When time’s up they lose control and can’t request it again.

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

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 Ferri’s connectivity is excellent and the most reliable of any panty vibrator I’ve tested, in both nearby Bluetooth and long-distance modes.

Pairing is fast and easy. The very first time is fast but takes a couple steps: tap “Add Toy,” turn the Ferri on, and it appears in the toy list to be added in seconds. After that one-time setup, the Ferri auto-connects immediately when you turn it on with the app open.

Once paired, the Ferri stays connected through normal phone behavior – locking the screen, switching to another app, or leaving Lovense Remote idle for long stretches doesn’t drop the connection.

It also stays connected through body interference like happens when a partner is controlling your toy from an angle or behind you. Water-rich materials like body tissue dampen Bluetooth signals more than walls or clothing, which is why some panty vibrators that handle solo app control fine still drop the connection during partner control.

Our body-interference test simulates this at three progressively harder positions, and the Ferri holds a stable connection at all three – including the most severe angle. Other panty vibrators like the Satisfyer Sexy Secret and NS Novelties Techno Lucy lose the connection at that worst-case angle. So if a partner controlling your toy with a lot of your body in the way is part of how you’ll use a panty vibe, the Ferri’s connectivity is excellent.

Bluetooth range came in around 190 feet in our open-air test (measured with a clear line-of-sight) before the connection dropped – well past the distance you’d likely cover during typical wearable use. Your own results may vary depending on walls and interference.

When a disconnect does happen (like if you walk out of range, or something briefly blocks the signal), the app reconnects automatically as soon as the signal is clear, and a red “Reconnecting…” indicator on screen shows the controlling partner that control has paused rather than pretending it’s still working.

Two settings also give you control over what the vibrations do during a disconnect: Auto-Stop pauses the Ferri until reconnection – useful for making sure the toy stays silent – or you can set it to keep the last vibration level running so stimulation isn’t interrupted.

The long-distance connectivity is also excellent. The long-distance connection works in two parts: the Ferri 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. So as long as your cell signal or Wi-Fi is decent, the long-distance connection works well. Sessions don’t drop unexpectedly, commands consistently take effect, and the connection survives normal phone behavior on either end (locking the screen, switching apps, backgrounding Lovense Remote).

It can be spotty if you’re continually switching from wifi to cell data. So if you’re in this situation, it’s best to start the call on cell data, which prevents the call from dropping.

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 Lovense Ferri 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 Ferri’s on-toy controls are limited by design – the toy sits inside your underwear during use, so you’ll typically rely on the app.

A single button cycles forward through three power presets and four vibration patterns; there’s no backward step, and the full power range is only available through the app. The three presets are programmable from the app’s “Adjust Levels” screen, so you can set them to whatever levels you like. I’d rather the patterns weren’t on the cycle – most people don’t use them, and they add more clicks when you’re cycling through power levels.

The button is easy to feel and press without looking. Pressing pushes the Ferri against your body, but the button sits further back from the clit-end than on most panty vibrators, so the pressure lands in a plusher, more comfortable spot than a lot of panty vibrators.

In practice, the on-toy button is mostly for turning the Ferri on and off – the app handles everything else.

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 Lovense Ferri stays securely in place.

The magnet allows you to position the Ferri in the best spot on your underwear for you and secure it in place. The Ferri’s magnet is very strong, and the Ferri’s body is lightweight, so there isn’t much weight working against the anchor. The magnet is strong enough to hold the Ferri through my hand. I can place the toy anywhere in my underwear it stays there.

When using the Ferri in bed, it doesn’t budge from where I magnet it. Leg movement when shifting between sitting, lying back, and rolling onto my side nudges the toy a little, but I never feel it slipping off my clit – any small repositioning is just to optimize the spot.

When wearing it around while walking, it wiggles side-to-side a bit, but the magnet holds securely – and this movement actually makes it feel more stimulating.

Heavy activity like running, squats, dancing, and jumping jacks is where the Ferri shifts the most. It bounces around a little with gravity on landings, but always snaps back to its original spot, never falls out, and stays in a stimulating place throughout.

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 Ferri is comfortable to wear in bed and during light activity, but its firm body and focused contact surface keep it just behind the most comfortable panty vibrators I’ve tested.

When walking or going up and down stairs, the Ferri shifts a small amount side-to-side, and that movement translates into a little extra clit stimulation, but also a little less comfort. The toy is small enough that I never have to adjust my walk, and the slight wiggle doesn’t bother me personally. But it’s noticeable, and it isn’t something you can really control.

In bed, it’s very comfortable. There are no sharp seams, and the slight curve lays the toy along my pubic area so it doesn’t pull off or tap uncomfortably as I shift around. The Ferri has no flex or squish, though, and the contact area is small. When I roll onto my side, I feel some pressure as my legs push the firm toy into my body. It’s not painful, just something I notice. And the firm, focused shape is what allows the vibes to transfer so well.

If comfort is the priority, both the NS Novelties Techno Lucy (app-controlled) and the VeDO Niki (remote-controlled) are more comfortable options. Just be aware, the Lucy’s app is much worse, and the Niki isn’t quite as strong as the Ferri.

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.

While the Lovense Ferri isn’t the quietest panty vibrator I’ve tested, it’s reasonably discreet.

It was just below the most-discreet tier of wearables in our Background Noise Masking subtest. In this subtest, I wear the vibrator and my partner listens from three feet away while we play pink noise through a speaker at preset volumes (56, 62, and 68 dBA). One of the Ferri’s oddities is that the lower settings have harsher, more uneven sound. Whereas the higher settings vibrate more cleanly and are less noticeable – even though their decibel readings are nearly identical at around 43 dBA each. So the Ferri’s middle and high vibration strengths were masked by our quietest background audio (56 dBA of pink noise). But to mask the lowest vibration setting, we had to increase the pink noise to our moderate level (62 dBA).

The Ferri had a similar pattern behind a closed bedroom door. For this part of the noise test, my partner listens from the other side of the bedroom 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 re-position the toy or move it around. Holding the toy instead of wearing it gives us the most conservative results.

My partner couldn’t hear it on low or high power. But he heard the middle setting – really only when I was moving the toy so the sound was changing. The middle has that more jarring quality and enough strength that it draws your ear; high power settles into a cleaner, consistent pitch – which is why high power is actually more discreet than the middle behind a closed door.

If you want a more discreet panty vibrator without giving up much power, the VeDO Niki (remote-controlled) is meaningfully quieter and is another one of the strongest panty vibrators I’ve tested.

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 Lovense Ferri lasted 168 minutes during our test continuously vibrating on its top power level – the longest of any panty vibrator. Plus, in actual use you’ll likely use the lower and middle settings too which will extend the battery life.

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 Lovense Ferri is easy to clean. It’s IPX7 waterproof, so you can rinse 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 Ferri’s build quality is excellent – I’ve had mine since 2020 and it’s still working exactly as expected. The toy is smooth, firm silicone on the side in contact with your body, with some plastic and magnetic portions on the other side. The magnet that anchors the toy is small but very strong. The seams are all tight, and the single button has a satisfying press without needing much pressure to activate.

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.
