The FemmeFunn Ultra Bullet is one of the most powerful bullet vibrators I’ve tested. It has a good range for those who prefer mid-strength to extreme vibration power.

The lowest level starts at a 4.5 out of 10 vibration strength. This power is effective yet gentle enough that it doesn’t feel overstimulating. It’s a versatile mid-strength setting I can comfortably enjoy as a warmup. Or I can make it feel more intense by adjusting my pressure. Many high-powered bullet vibrators like this do not have a soft enough starting level, so I appreciate this about the FemmeFunn Ultra Bullet.

If you need especially gentle warmup levels, consider the BMS Swan Maximum or Pillow Talk Racy. But most people will find the Ultra Bullet’s starting level comfortable.

The second power level hits an 8 out of 10 vibration strength, which is quite a jump – nearly twice as strong. But after I spend some time warming up on that first power level, I’m ready for the intense second setting. 

The FemmeFunn Ultra Bullet’s final intensity level reaches 9 out of 10 vibration strength, which I consider extreme. Only a couple bullets, like the BMS Swan Maximum, reach a more intense strength, but few people will want more power. I rarely even use the FemmeFunn Ultra Bullet’s top setting (I typically finish on the second level), but power queens will love it.

The Lovense Ambi has an outstanding power range. It begins gently, climbs through moderately powerful middle levels, and reaches an intense top setting.

The Ambi’s top strength of 8.0 out of 10 is plenty for me. It has comparable power to my favorite mid-sized vibrators like the Lelo Mona 2 or Lovense Hyphy. Often, I orgasm on one of the upper-middle levels, never reaching the top setting, as I enjoy moderate strength.

The Ambi’s lowest power setting is a 1.5 out of 10 vibration strength, which is very soft. The Lovense Ambi’s wide power range is great for anyone who needs milder settings while warming up to avoid overstimulation.

There is a quirk to be aware of: in order to access the Lovense Ambi’s full power range, you’ll need to use the Lovense app. Using the app, you can gradually adjust the power in tiny increments from its low power of 1.5 to its top strength of 8.0. This is great for anyone who finds large steps distracting.

However, just 3 preset power levels are accessible using the button on the Lovense Ambi’s base. But you can set the 3 levels to whatever strength you want. Just navigate to the “Adjust Levels” screen in the Lovense app and set each setting to your preferred intensity.

I love the default preset levels and haven’t changed mine out, but you can if you want to!

We rate vibrations that are rumbly higher than those that are buzzy because it’s what most people prefer. However, others prefer buzzy vibrations, so consider what you enjoy!

The FemmeFunn Ultra Bullet only has passable rumbliness because just the first power setting is in the rumbly range. The two higher powers are buzzy. I personally enjoy moderately buzzy vibrations – especially in a bullet vibrator. So I love the FemmeFunn Ultra Bullet. It’s all based on your personal preference.

Powerful, buzzy vibrations tend to feel especially intense. So, if you’re unsure whether you prefer rumbly or buzzy but know that you like intensity, this could be the perfect choice! 

If you enjoy rumbly vibrations more, you’ll prefer the We-Vibe Tango X, though it is a bit more expensive. If the cheaper original We-Vibe Tango is available, snatch that up because it’s no longer in production but is the most affordable bullet with powerful, rumbly vibrations.

We rate rumbly vibrations higher than buzzy ones because it’s what most people prefer.

The Lovense Ambi has a pretty good amount of rumbliness. The first half of the power range feels rumbly. Then, the stronger half of the power levels feel neutral or moderately buzzy.

If you love rumbly vibrations, you’ll have some settings to enjoy on the low to mid-powered end, but nothing strong and rumbly. If you want comparable power with deeper vibrations, consider the We-Vibe Tango X.

But I actually love the feeling of neutral or somewhat buzzy vibrations in a bullet vibrator. When vibrations have enormous power, like large wand vibrators do, buzziness makes them feel overwhelming. That’s why I prefer rumbly wands like the Magic Wand Rechargeable over buzzy ones like the Doxy Die Cast 3.

But the intensity of small bullet vibrators is moderate in comparison. Some buzziness in a bullet vibrator adds a kick at the surface that helps me orgasm more easily. As a result, the Lovense Ambi is one of my favorite bullet vibrators. It has plenty of settings toward the center of the spectrum, from moderately rumbly to moderately buzzy, that I really enjoy.

Whether you enjoy pinpoint or broad stimulation is entirely a personal preference.

The FemmeFunn Ultra Bullet is between broad and focused stimulation. Its tip is nearly an inch wide, which is broader than most bullets with lipstick-shaped or tapered tips (like the We-Vibe Tango X or Nasstoys Intense Travel Vibe Mini). However, it’s more focused than palm vibrators like the We-Vibe Touch X or Dame Pom.

The FemmeFunn Ultra Bullet also has a rounded tip, making it feel slightly broader than a typical bullet. This is useful and comfortable if you prefer firm pressure because it’s less pokey than pointed tips. You can also use the side of the bullet to disperse the vibrations a bit.

The Lovense Ambi is generally slightly broader than most bullet vibrators but still more precise than other vibrators. And its unique shape lets you vary the precision of the stimulation.

The Lovense Ambi’s rounded head is 1.04 inches wide, whereas the famous We-Vibe Tango X is just 0.69 inches wide – much more precise. The Ambi’s slight extra width is great for those who enjoy applying firm pressure because you can hone in on a fairly small area while still spreading the pressure out more comfortably than a narrow bullet vibrator.

The rounded head also has a subtle lip that you can use to make the stimulation more precise. You can use the tip on the back of the toy for very focused stimulation. However, I’ve found that using the back tip positions the Ambi at a more awkward angle. The motor is also closer to the rounded end, so I use that side. If you want even broader stimulation, you can press the long, flat end against your whole vulva, too.

Do what works for you – the unique shape provides much more variation in how you can use the Ambi than most bullet vibrators.

The Lovense Ambi’s app has incredible features for close-range play. I’ve tried many remote and app-controlled vibrators, and Lovense has the best app – it’s the most feature-rich, is the easiest to use, and has the best connectivity (discussed here).

The Lovense app gives you detailed control of the Ambi’s vibrations. Using the “Remote” feature, you can set the Ambi’s power to your precise, preferred strength. Simply raise or lower the on-screen dot to incrementally adjustment the vibration strength.

Press the “Float” button to hold the power at that intensity. Or click “Loop” to easily create a repeating pattern in the moment. You can also create a pattern you enjoy and save it to use again later. We’ve found pattern creation in other apps like We-Vibe to be much clunkier than Lovense’s simple, intuitive implementation.

You can also connect multiple Lovense toys simultaneously and control each toy within the app. The Lovense screen will provide a separate control dot for each connected toy. So if you have a wearable G-spot vibrator like the Lovense Lush 3 or Lovense Vulse, you can control it while using the Ambi on your clit.

You can browse through unlimited patterns that other Lovense users have created and shared in the “Discover” section and save them to your own frequently used library under “My Patterns.” Adjust the speed of each pattern to make it just right for you!

You can also use the Music and Sound features to control the Ambi’s vibrations using music saved on your phone or sound picked up by your phone’s mic. You used to be able to control the Ambi using Spotify, but Spotify discontinued support for third-party apps in 2022.

You can also adjust how sensitive the Ambi is to the music or sound so that the noise must be louder for the Ambi to vibrate.

You can also set an alarm so your Ambi vibrates at a certain time. However, this feature is more useful for Lovense’s wearable vibrators like the Lovense Lush 3 or Lovense Ferri. It’s unlikely you’ll wake up holding the Lovense Ambi in just the right spot!

The Lovense app’s long-distance features (and connectivity discussed below) are also the best of any long-distance vibrator.

Using the Lovense app, a long-distance partner can control your Ambi from anywhere in the world. They’ll use the same “Remote” screen that you have when controlling the Ambi nearby using Bluetooth. The functionality is not reduced for long-distance play like it is with Satisfyer’s app (which is used to control the Satisfyer Ultra Power Bullet 8).

Your long-distance partner can set the exact vibration strength they want using the “Float” feature, and they can quickly and easily create a pattern for you to enjoy using the “Loop” function. They can also send you predesigned patterns they’ve created or other Lovense users have shared.

You can video chat or message with your long-distance partner within the Lovense app while they control your Ambi. You don’t need to use a separate messaging or video chat app. You can minimize the control panel to see your partner more clearly in the video feed.

Or, if you feel more comfortable without video, you can turn off your video feed and mic at any time. Or simply share control of your toy without a voice or video call.

You can also share control of the Lovense Ambi’s vibrations without allowing video or sound in the first place. This feature is especially useful for those who want to give control to an anonymous long-distance partner. You can generate a one-time control link for a set amount of time and anonymously send it.

Once time is up, that person cannot request control of your Lovense Ambi again unless you send them another link.

For a partner you’ll play with repeatedly, simply save their username to your saved partners list. You can also save multiple partners. If your partner also has a Lovense toy, you can simultaneously control each other’s toy.

Lovense also offers several partner settings unique to its app. For instance, you can allow a particular partner to control your Ambi without requiring them to request permission first, which helps you connect more quickly.

The Lovense app easily provides the most intuitive and feature-rich long-distance experience!

The Lovense Ambi’s connectivity with the app is extremely reliable. Lovense has the best connectivity – during both nearby Bluetooth control and long-distance control.

Connecting the Ambi to the Lovense app is quick and easy. The first time you connect, you’ll need to add the Lovense Ambi to your list of toys, which takes less than 20 seconds. Once you’ve added the Ambi, it typically connects immediately and automatically when you open the Lovense app.

Once connected, it rarely disconnects. I regularly play without any disconnections, even if I lock my screen or use other apps for extended periods.

If it loses connection, the Lovense Ambi usually re-pairs automatically, so it’s not very disruptive. Lovense is the best app-controlled brand for a smooth experience.

It also holds its close-range Bluetooth connection from a good distance (155 feet in our test). My partner and I tested the Bluetooth distance in the alley behind our house. I had my partner connect his phone to the Ambi and walk down the alley, continually changing my Ambi’s vibrations as he walked away. When the connection dropped we measured the distance (155 feet).

The Lovense Ambi also remains reliably connected during long-distance play as long as you and your partner have good Wi-Fi or a strong cell signal. Lovense’s long-distance features are not glitchy like We-Vibe’s often are.

This is how the long-distance connection works: the partner with the Ambi connects the vibrator to their phone using the typical Bluetooth connection – the same way you connect for nearby play. Since the Lovense Ambi’s Blutooth connection is excellent, this part of the long-distance connection is excellent too.

Then, your long-distance partner’s phone communicates with your phone over Wi-Fi or cell data to control the Ambi from afar—just like you and I are communicating long-distance over the internet right now. So, as long as you both have good Wi-Fi or cell signal, the connection is great.

For reference, my partner and I rarely, if ever, have an issue connecting long-distance in Lovense’s app. You don’t need outstanding internet – good is good enough!

The FemmeFunn Ultra Bullet is very comfortable and fairly easy to adjust the settings. The flexible core makes the pressure against your body feel plush despite its firm tip. And even though the form is not rigid, it’s easy to slide a finger near the tip to apply more pressure.

If you use your fingers near the motor, the vibrations travel into your fingers, but it’s not distracting unless you’re particularly sensitive to this. The Ultra Bullet’s comfortable width and above-average length make it easy to grip and maneuver wherever you want.

The FemmeFunn Ultra Bullet uses one button to cycle through the 3 intensity levels and all 17 vibration patterns. I prefer toys with separate controls to move forward and backward through settings. But the Ultra Bullet’s one-button system is much more user-friendly than most one-button bullet vibrators. Here’s why:

The FemmeFunn Ultra Bullet has a memory system. This means if you turn the toy off after using a pulsing pattern, it will start again on that pulsing pattern when you turn it back on. That way, you don’t have to tap the button 10+ times to return to your favorite setting.

But it also makes it easy to return to the softest steady vibration. After turning the toy on and automatically returning to the most recently used setting, the next button click will bring you back to the lowest power level. 

This makes it easy to return to my warmup intensity when necessary. Then, I can work my way back up. So it’s set up with the natural rhythm your body wants to take and saves you from another slew of taps to get back around to the start again. 

It’s still not as convenient as bullets with separate buttons to change power and move through patterns, like the We-Vibe Tango X. But the FemmeFunn Ultra Bullet’s unique system makes it much better than other one-button cycling bullets I’ve tried.

The Lovense Ambi is a very comfortable and easy-to-use bullet vibrator.

When I use vibrators, I press them firmly into my body. Because the Lovense Ambi has an angled head, leveraging it and applying pressure is much easier than it is with most bullet vibrators. This unique shape can be a little more awkward to hold than a straight bullet, but it helps leverage the Ambi to maintain good clitoral contact without taking up much space. And it’s still comfortable – it just takes some getting used to.

Like most bullet vibrators, the motor is close to your hand because the toy is so small. So some vibrations travel into your hand, but the silicone handle helps dampen them. They’re minimal, so I don’t find them distracting.

You can control the Lovense Ambi using the button on the base of the handle or through the Lovense app. The physical controls are just okay. It’s a single button, so you have to cycle through the 3 programmed intensity levels (which you can set in the app) and the 4 vibration patterns.

I don’t find it annoying since there are not too many settings. But if you frequently change power levels or patterns, you’ll want to control the Ambi using the app. You can access the Lovense Ambi’s full power range in the app and quickly move between settings and patterns.

The FemmeFunn Ultra Bullet is fantastic during sex. It’s a great size to leverage without bumping into your partner and fits easily into tight spaces. 

The flexible form is beneficial when there’s a lot of movement because it moves along with your body instead of bumping against your pubic bone. So it stays comfortably in contact with your clit, providing excellent stimulation.

The Lovense Ambi is excellent during sex.

The angled head helps the Ambi slip easily between your legs without the base of the handle sticking out too far. This way, your hand doesn’t interfere with your partner’s body. You’re more limited when trying to angle and leverage a straight bullet vibrator during sex.

The rounded head distributes the pressure very comfortably. And its moderate width makes it easier to keep it in contact with my clit during sex than narrow bullet vibrators. The only reason I didn’t rate the Ambi a perfect 10.0 is that the handle is shorter than some. So, it can become tiring to hold after a while if you’re pressing hard.

But overall, it’s one of my favorites to use during sex.

The FemmeFunn Ultra Bullet is reasonably quiet. The decibel measurements we recorded for the FemmeFunn Ultra Bullet were softer than average. 

We also test whether someone on the other side of a closed bedroom door can hear the vibrator. My partner could not hear the FemmeFunn Ultra Bullet on low or medium strength. On its highest setting, my partner thought he could barely hear it. But this was his note: “I had to listen very closely and wait for any sounds outside to become extremely quiet. Even then, I could just barely make it out occasionally. I doubt anyone would actually hear it in normal use.” 

Considering it’s one of the most powerful bullet vibrators I’ve tested, the Ultra Bullet’s noise performance is pretty good. And to be safe, you can turn on a box fan or play music in the bedroom to ensure no one will hear it.

I’m also pretty sensitive to noise, and the Ultra Bullet’s sound doesn’t bother me at all. So, it’s a safe option if you’re distracted by sound.

The Lovense Ambi is very quiet. I can use every power setting, and my partner cannot hear it from the other side of the bedroom door. It’s definitely discreet enough if you share a wall with a housemate.

The buzzing sound itself is also mild and not distracting if you’re easily taken out of the mood by sound.

The FemmeFunn Ultra Bullet is rechargeable and lasted 85 minutes, constantly vibrating on high power during our testing. This is great for a bullet of this immense strength. I frequently forget to charge between uses, and it still has plenty of remaining battery.

The Lovense Ambi is rechargeable and has an acceptable battery life. I charge all my vibrators fully, then run them on their highest setting until they die. The Lovense Ambi lasted 55 minutes.

This is below the average bullet vibrator’s battery life. But since I typically don’t go up to the top strength, I can make the Lovense Ambi last longer. 55 minutes is still plenty for most people, but you’ll want to charge it between uses.

I’d recommend the We-Vibe Tango X if you want something about this strong that lasts longer.

This bullet has a great build quality. The body-safe silicone is smooth yet has a slight, comfortable grippiness to it that I enjoy. The ABS plastic frame beneath the silicone feels solid. The flexible areas feel a little squeaky but seem sturdy, and I’m not afraid they’ll break when I’m applying pressure.

The Lovense Ambi has fantastic build quality. There are no seams, and it’s completely covered in smooth, body-safe silicone. It’s not flimsy, and the button is easy to press and feels high-quality.

This FemmeFunn Ultra Bullet is IPX7 waterproof. This means you can completely submerge it, making it easy to clean. Just wash in the sink with soap and warm water.

The Lovense Ambi is very easy to clean because it’s completely IPX7 waterproof. You can fully submerge this while scrubbing with soap and water.
