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 Satisfyer Ultra Power Bullet 8 is low to mid-powered. It’s a very budget-friendly option if you don’t need anything stronger than a 5 out of 10 vibration power. This bullet is powerful enough for me to orgasm, but it takes some time.

Its 5 intensity levels begin softly with 1.25 out of 10 vibration strength. So, it provides several gradual power increments to enjoy in the mild range. This will satisfy people who prefer soft vibrations but not those seeking strength.

If you enjoy more intense vibrations, I recommend spending a few extra dollars and upgrading to the Pillow Talk Racy. This bullet starts at 2 out of 10 on low and reaches 7.75 out of 10 on high, with lots of gradual steps between. So you still have plenty of gentle levels as a warmup but can finish with more intense stimulation. Or at the same price, the BMS Swan Maximum Bullet has an even better power range, but it’s somewhat uncomfortable to grip so I prefer the Racy.

If you want more intense stimulation with app-control, you’ll need to upgrade to the Lovense Ambi.

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 (low-frequency) vibrations higher than buzzy ones because most people prefer rumbliness. So, if you prefer buzzy vibrations, simply disregard our scoring in this area and choose based on what you enjoy! 

The Satisfyer Ultra Power Bullet 8 is a buzzy vibrator. 

Only the lowest level is rumbly. And since it’s the weakest setting, most people will only use it briefly while warming up. The top 3 settings where you’ll likely spend most of your time are buzzy. If you love buzzy vibrations, this may be a great fit! Though I enjoy the Satisfyer Ultra Power Bullet 5 (not app-controlled) more because it’s a bit stronger overall, and I like a bit more kick behind my buzzy vibrations.

If you’re like most people and prefer rumbly vibes, you’ll have to increase your budget slightly. The Pillow Talk Racy is the most affordable rumbly bullet vibrator. Or if money’s no object, the We-Vibe Tango X is my most rumbly bullet.

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 Satisfyer Bullet 8 has a cone-shaped tip that provides somewhat versatile precision. You can get extremely precise stimulation when using the tip’s point on your clit. Or get a more moderate amount of precision when pressing the angled section to your body.

I use the angled method since I prefer indirect stimulation. But its unique shape allows you to vary the surface area in contact with your body to meet your preferences.

With Satisyfer’s affordable prices, I’m always impressed with their app’s excellent quality. Satisfyer’s app outperforms every more expensive brand except Lovense. 

The Satisfyer Connect app provides a wide variety of practical, in-depth, and intuitive ways to control your Satisfyer Ultra Power Bullet 8 from nearby using Bluetooth. Jump here for a discussion of its connectivity (which is also excellent).

If you like having complete control over your vibrations, use the “Live Control” mode. You can raise and lower the intensity by swiping up and down on-screen. This provides access to a continuous, gradual power range (instead of stepping through just 5 levels with the on-toy button). Or you can draw your exact vibration pattern. Select “Loop,” and the Satisfyer app will put your pattern on repeat. 

If you love your in-the-moment creation, you can save it. The next time you use the Ultra Power Bullet 8, your pattern will be available under “Program Play.”

The Program Play screen also provides over 30 preset patterns to enjoy. Select any pattern and control its intensity with a swipe of your finger on-screen. And you can find even more patterns through the “Community” feature. This is where other users share patterns they’ve created, which you can use.

The “Ambient Sound” feature uses your phone’s mic to make the bullet buzz along with the noise around you. For wearable vibrators like the Satisfyer Sexy Secret and other vibrating panties, it’s a great setting to use in a clubbing environment. But for at-home play with a bullet, it could be a nice encouragement to get a little vocal! 

You can adjust how strong the vibes respond to the sound around you by dragging up or down on the screen.

Or buzz along to your favorite songs through the “Music Vibes” feature. You can select from songs saved on your phone or connect to Spotify.

Satisfyer also has a “Remotyca Stories” library, which allows you to vibrate in sync with spicy stories, but the selection is limited.

Lastly, in 2023, they added a “High Touch Meditation” feature. This feature provides relaxing audio meditation recordings guiding you slowly through using your vibrator, encouraging you to connect with your body and relax. Over the guided meditation, it plays soothing soundscapes like you’d hear at Yoga or while getting a message. The Satisfyer bullet will vibrate at the appropriate moments in the guided meditation.

The first series of meditations released guides you through using an air pulse toy like the Satisfyer Pro 2, so they don’t have a series specifically for the Satisfyer Ultra Power Bullet 8 yet. But the Power Bullet will still vibrate to the meditation – you can still follow along and simply ignore the parts that aren’t directly applicable to a bullet vibrator.

The Satisfyer Ultra Power Bullet 8 also lets you connect with a long-distance partner anywhere in the world. And Satisfyer’s long-distance experience is great, though less fully-featured than in nearby Bluetooth control.

You can video chat with your partner while they control your Power Bullet 8. When a long-distance partner controls your Satisfyer bullet, they can set your exact vibration power or create their own patterns. In long-distance mode, your partner doesn’t see the precise vibration pattern on-screen, as you do in nearby Bluetooth mode. So drawing an exact pattern is trickier in long-distance mode. But overall, it’s still an excellent level of control.

You can also turn off the video feed or mute the mic, if you’d rather a long-distance partner not see or hear you. This is useful if you want to connect with someone anonymously with just your username. You can also send texts or photo messages through the app – even adjusting how long someone can view your message.

If your long-distance partner also has a Satisfyer toy, you can simultaneously control each other’s toys. Either of you can end toy control or the call at any time. 

With a bullet like the Satisfyer 8, it’s a great way to relinquish control of the vibrations to a partner while remaining in control of the pressure and placement you need to orgasm.

The Satisfyer Ultra Power Bullet 8’s connectivity with the app is excellent. 

Pairing your Satisfyer Bullet 8 with the app is quick and easy. It takes less than 20 seconds, and the app walks you through exactly what you need to do to connect the two. I rarely have any issues with this. But even if I do, the app gives detailed directions to get you back on track.

Once it’s paired, it typically stays paired. And even if it does disconnect (possibly due to separating the toy and phone or leaving the app untouched for too long), it takes minimal effort to get things re-paired. Often, it reconnects immediately on its own.

This is true whether I play solo or with a partner through the long-distance feature.

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 Satisfyer Ultra Power Bullet 8 is a comfortable bullet vibrator and easy to use. At 5.5 inches, it’s one of the longest bullet vibrators I’ve tested, making it especially easy to leverage and comfortable to grip. You can apply firm pressure with it, and vibrations in your hand are minimal.

The uniquely shaped tip may take some getting used to, but you can get great contact and stimulation from it.

The button placement is unusual – away from the handle, very near the tip. I have to adjust my grip to click the button when using the bullet. But the button presses easily, and it isn’t a hassle. 

However, I wish it had separate buttons to increase and decrease power. Since it has just one button, you must cycle through all 5 power levels and 7 vibration patterns on a loop. Since there are so many settings, finding the one you want takes time. However, you can avoid this hassle by controlling the bullet through the Satisfyer app, which gives you quick, detailed control.

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 Satisfyer Bullet 8 works best in the spooning position or others where you’re not facing your partner. It’s easy to maneuver and has a small tip, which fits easily in tight spaces. 

However, the unique cone-shaped tip makes it harder to use in missionary positions or others facing your partner. The dramatic taper limits the surface area that can contact your body without sharply angling the entire bullet. But angling it more is difficult without the handle beginning to interfere with our bodies.

It’s still doable, but I prefer the rounded ends of the Pillow Talk Racy, Lovense Ambi, or FemmeFunn Ultra Bullet in face-to-face positions.

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 Satisfyer Bullet 8 is completely inaudible from behind a closed door on all power levels. So it’s safe to use if you live with housemates. 

The decibel level is technically a little louder than some, but I don’t find the sound distracting. However, if you’re especially sensitive to this, there are quieter options.

The Pillow Talk Racy is a budget-friendly, discreet bullet with quieter decibel levels.

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 Satisfyer Ultra Power Bullet 8 has a great battery life. It lasted an hour and 45 minutes, continuously vibrating on high power during our testing. However, since it’s weaker than many bullet vibrators, the long battery life is not that impressive.

For instance, the We-Vibe Tango X has a comparable battery life while packing over 1.5 times the power.

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 Satisfyer Bullet 8 has a smooth silicone tip and plastic body. Everything seems well put together, but it’s a light toy, contributing to a slightly cheap feel.

I’ve had no issues with performance, but it won’t provide the more luxurious feel of pricier options like the We-Vibe Touch X or Lovense Ambi.

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 Satisfyer Ultra Power Bullet 8 is super easy to clean. It’s IPX7 waterproof, which means you can safely submerge it up to a meter deep for up to half an hour. So you can clean it easily with soap and water or bring it with you in the bath.
