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 Romp Party’s clit-motor power and rumbliness in-depth.

Here’s the main conclusion:

The Romp Party falls in the middle of the panty-vibe pack on clit stimulation. Its motor is technically strong, but the straight design doesn’t transfer enough of that strength to my clit, and the vibrations are buzzy on the settings I actually use. In this price range, for a more stimulating panty vibe, go with the VeDO Niki if you want a physical remote, or the NS Novelties Techno Lucy if you want an app.

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 Romp Party has one of the strongest top settings of any panty vibrator I’ve tested, though its design doesn’t transfer all of that power to your clit. The motor reaches a 9 out of 10 in vibration strength at its highest setting. Of my panty vibrators, only the Lovense Ferri reaches a higher top power. The Romp Party is just behind it. Spread across 7 distinct power levels from a gentle 1 out of 10 warmup up to that 9 at the top, it has one of the widest power ranges of any panty vibrator in this price range.

But with a wearable, you can’t press harder for more intensity the way you can with a handheld – the toy’s shape and fit has to naturally deliver the motor’s strength to your body. This is where the Romp Party’s design works against it. Its strongest vibrations are at the middle of the toy rather than at the clit where most panty vibrators concentrate them, so I had to situate it up higher in my underwear to feel more of the vibrations. This felt a bit unnatural, and my underwear kept trying to push it out of that placement.

The Romp Party is also straight rather than contoured, so it doesn’t sit snugly against my clit the way better-fitting panty vibes with a curve do, like the Lovense Ferri and VeDO Niki. When I get the placement right, it’s reasonably stimulating, but getting it right takes more effort than I want from a hands-free toy and requires frequent readjustments.

So the Party feels less stimulating than the raw 9 out of 10 strength suggests. If you want a panty vibe in this price range that delivers more of its motor’s strength to your clit, the VeDO Niki is a better option – its top setting is a notch lower at 8 out of 10, but its body-contoured shape gets more of that power where you actually feel it, so I can orgasm with it hands-free. For the strongest motor and best vibration transfer of any panty vibrator I’ve tested, try the Ferri for about $40 more.

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 most people prefer them, but it’s genuinely a personal preference.

The Romp Party is not very rumbly.

Its lowest power level is technically extremely rumbly at 59 Hz, but that’s the warmup setting – too gentle for the rumbliness to feel very stimulating. From there, frequency climbs as power does: the toy is moderately buzzy by its mid-range at around 100 Hz (about average for a panty vibe), and extremely buzzy at 127 Hz at the top. Since the vibrations don’t transfer well, I need to crank the power to feel anything, so most of my use with this toy is in the buzzy range.

If you care about rumbly vibrations, the VeDO Niki is one of the only truly rumbly panty vibrators and it’s an excellent choice in the same price range.

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 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 Romp Party 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 Romp Party’s remote features and connectivity.

Here’s the main conclusion:

The Romp Party has a basic, reliable remote – stable connection, instant response, and separate + and – buttons to adjust the power. Remotes can be useful if you don’t want to use a phone to control your toy.

Its main limitations are typical of remotes versus apps: less partner feedback and shorter range. If you want this more-detailed control, go with the Lovense Ferri for the best app control, or the NS Novelties Techno Lucy for a budget-friendly app experience.

The Romp Party’s remote is simple, but works well – the two-button design gives all the control you’d need for power adjustment. Its few minor downsides are typical of remotes in general compared to apps.

Power control is fast and direct – the dedicated + and − buttons let you move forward and backward through seven power levels, and there are no vibration patterns to cycle through at all, which keeps the remote uncluttered. And you won’t accidentally switch from a constant setting to a pulse or wave.

The remote is comfortable to hold – a good size, fits easily in my hand, and the buttons are easy to tell apart by feel so I don’t have to look at the remote. This is a big upside compared to an app-controlled toy if you don’t want you or a partner to have to be tied to a phone. With the Party, you can make adjustments from your pocket without looking.

Like most panty-vibe remotes, the Romp Party’s partner feedback is just a faint blink when you press a button – there’s no way to tell what setting the toy is on. That’s fine if you’re using the toy yourself, and many partners won’t mind. But others find it less engaging when they can’t tell what the toy is doing or what you’re feeling.

An app-controlled panty vibe gives your partner real-time visuals of the toy’s vibrations, which can make controlling it feel more engaging. If that’s a priority for you, the Lovense Ferri is the best app-controlled panty vibe.

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

The remote maintains a reliable connection through typical interference. Body tissue between a remote and toy is the main thing that typically breaks a remote’s signal during partnered control. Remote’s signals are weakened by water-rich materials like your body sitting between the remote and your toy.

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

Button presses register instantly – the toy reacts before my finger even lifts off the button. And the remote is always connected, so there’s no reconnection routine when starting to play.

One quirk: occasionally a click sounds as if it went through but the click was too light or off-center to make it actually take affect. You do have to give a deliberate, full press of the button.

The remote reaches about 55 feet in our open-air range test – measured with clear line-of-sight and no body interference. This is middle-of-the-road for the wearable vibrators’ remotes we tested, and real-world range will likely be shorter once objects and body interference come in. But the Romp Party has comfortable headroom for most activities, and especially any same-room use. If you need an especially long range, many app-controlled toys stay connected much 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 panty vibrators, the Romp Party’s on-toy controls are limited by design – the toy is inside your underwear during use, so you’ll typically rely on the remote.

There’s a single button on the toy that cycles forward through the seven power levels, with no patterns mixed into the loop. Unlike the remote, there’s no minus button – dropping back to a gentler setting means clicking forward until you start over in the cycle. Since there’s not many settings it doesn’t take too long to cycle, so the controls work fine if you also want to occasionally use it like a handheld vibe.

The button is well-placed: easy to feel and press without looking, and centered in the middle of the toy rather than tucked at the top the way most panty-vibe buttons sit. Pressing it does push the toy against you, which some people may find slightly uncomfortable, but the mid-toy placement distributes the pressure more evenly across your body than a button near your clit would.

The on-toy button works fine as a backup, but the remote is the main way you’ll use the Romp Party.

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 Romp Party’s secure fit is great in bed but gets worse with activity. It’s much more secure than panty vibrators without a magnet that just sit loosely in your underwear. But its long, straight body doesn’t curve along your vulva, so it shifts off my clit more easily during walking and moves around during heavier activity than curved toys – even though the magnet keeps the toy itself anchored to my underwear.

In bed, the magnet locks the toy to my underwear and doesn’t slip from where I position it. The toy moves a bit with my body when I shift around, but it stays anchored and keeps a good position for stimulation fairly easily – you’re generally not moving around a ton here so the toy doesn’t shift off your clit that much. Form-fitting underwear helps; loose underwear lets the toy bounce against me more.

Walking is where the design starts working against the toy. The toy stays anchored to the underwear, but it doesn’t press as firmly against my body as panty vibes that curve with your vulva and it wiggles around more easily – so contact between the toy and my clit goes from solid in bed to only decent during light activity like walking around. When wearing a thong, the toy is long enough that the back end can poke out of the underwear as the toy starts to shift; full-backed underwear keeps that from happening.

Heavier activity is the hardest test. Running and jumping jacks bounce the toy around enough that stimulation drops off even more. It doesn’t fall out, but it’s not a good experience.

The magnet design is part of why this toy shifts more. It’s a small disc with decent strength, but it’s not big enough to anchor the long body of the toy completely and prevent the end from swinging around as I move. Still, the magnet is a clear improvement over panty vibes that just tuck into your underwear.

If you want a panty vibe that stays put while you move, the VeDO Niki is a better option in this price range – its body curves, so it stays firmly against your clit during walking instead of shifting off the way the Romp Party does.

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 Romp Party is comfortable in bed if you like focused, slim contact against your clit, but it shifts around enough when walking to cause some slight discomfort.

In bed, I’m not moving a ton, so the toy sits consistently against my body. The silicone is soft and smooth with no poke-y spots. While the contact is more focused than what I get from broader, contoured panty vibes, the pressure stays light enough to feel comfortable.

When walking, the slim, straight shape moves around more than a broader or contoured toy would. The materials are still smooth and there’s no pinching, but the toy taps against my clit a little more than I’d like. If wearing it with a thong, the back end sometimes sticks out of your underwear which is a distracting feeling.

For comfort, both the VeDO Niki and the NS Novelties Techno Lucy are better picks in this price range – each is more form-fitting to keep the toy from shifting uncomfortably.

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 Romp Party is in the most discreet group of wearable vibrators I’ve tested. However, more stimulating panty vibrators like the VeDO Niki and NS Novelties Techno Lucy are similarly quiet, so they’re better options for most people.

The Romp Party’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 Romp Party never measured higher than this.

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). He couldn’t hear the Romp Party at any vibration strength under any of the three tested volumes of background noise. It’s audible in our room without any pink noise playing – but every wearable I’ve tested is, no matter how gentle and quiet its vibrations are.

For the closed-door part of the test, my partner listens directly outside our bedroom door while I use the toy in bed. I use it like a handheld toy here, since wearing dampens sound and some people want the flexibility to safely re-position the toy or move it around. Holding the toy instead of wearing it gives us the most conservative results. He couldn’t hear the Romp Party from behind the door 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 Romp Party has long battery life – much longer than typical for a panty vibrator in this price range. It lasted 115 minutes at its highest power during our test, more than twice as long as the comparably-priced VeDO Niki and NS Novelties Techno Lucy (both 55 minutes).

If you want even longer, the Lovense Ferri runs about 2.8 hours at top power. It’s pricier than the Romp Party but is a much better panty vibrator overall.

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 Romp Party is easy to clean. It’s fully waterproof – rated IPX7, so you can rinse it under a running faucet or fully submerge it without worry.

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 Romp Party’s build quality is decent for the price, but a step behind most panty vibrators I’ve tested. It’s coated in a nice silicone with a slight flex to the core, and the on-toy and remote-control buttons each have a satisfying click feel. The plastic remote feels fairly sturdy too even though it’s quite lightweight.

The weak spot is the magnet that holds the toy to your underwear. It has decent grip when seated, but it protrudes far enough from the toy that it’s easy to knock off by accident – and the same small magnet is what struggles to anchor the long, stick-straight body during heavier movement.
