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

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

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

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

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

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

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

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

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

Like all panty vibrators, the 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.

In the next sections, I’ll cover the Flexer’s G-spot vibration power, rumbliness, and flexing motion.

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

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

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

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

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

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

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

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

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

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

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

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

In the next sections, I’ll cover the 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 the Lovense app’s close-range features, long-distance features, and connectivity in detail.

Here’s the main conclusion:

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The 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 Lovense Flexer doesn’t include a physical remote control. A remote lets you adjust the toy by feel – without pulling out your phone.

• 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.

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

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

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

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

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

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

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

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

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

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

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

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

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

In our background noise masking test, I wear the toy while my partner listens from three feet away and we play pink noise through a speaker at quiet, moderate, and loud volumes. Even with our loudest background audio playing all the Flexer’s settings were audible – low power was barely noticeable, but middle and high were still unmistakable.

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

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

The 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.

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

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

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

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

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

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