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 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 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 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 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 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 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 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 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.

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 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.

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 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 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).

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 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 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. Our body-interference test simulates this scenario at three progressively challenging angles, and the Niki holds a stable connection through all of them. Our test runs harsher than typical real-world conditions, so partner-controlled play 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 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 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.

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 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.

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 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 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.

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 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.

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 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 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.

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 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 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.
