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 Je Joue Rabbit Bullet has a nice power range but only offers gentle through moderate strengths. It’s best for those who prefer mild stimulation.

The Je Joue Rabbit’s lowest setting is a 1 out of 10 vibration strength, which is very gentle and great for a warm-up. You climb comfortably through 5 power levels to its top strength of 5.4 out of 10. This is strong enough that I can orgasm with the Je Joue Rabbit Bullet, but only if I press the vibrator’s firm core to my body.

The motor is located in the bullet vibrator’s core – not in the rabbit ears. So the rabbit ears just pass along the vibrations from the main part of the bullet. As a result, stimulation from the rabbit ears feels weak. And they feel even weaker the harder you press since they cannot flutter around.

People who prefer gentle stimulation may enjoy this bullet. If you like more power, consider a bullet like the We-Vibe Tango X, which offers rumbly vibrations, or the Lovense Ambi, which offers more neutral vibrations.

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.

Je Joue’s bullets are generally known for being rumbly, but the Je Joue Rabbit Bullet has mediocre rumbliness. The first three settings feel deep, but the top two strengths have a “neutral” feel. The Je Joue Amour and Je Joue G-spot Bullet are certainly more rumbly.

I enjoy neutral-feeling vibrations personally, so I don’t mind this about the Je Joue Rabbit, but those specifically looking for rumbliness will not be satisfied. You can find some better options at this price point, including Je Joue’s other bullets. Or the We-Vibe Tango X has exceptional rumbliness and is only a few dollars more.

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.

Compared to other bullets, the Je Joue Rabbit’s stimulation is between focused and broad (a personal preference).

It’s about 1.11 inches from edge-to-edge of the rabbit ears, which is broader than many bullets. I use this measurement because I’ve found you feel the rabbit ears together. I expected the stimulation to feel like two distinct, focused points, but that’s not the case. Your body cannot feel that there are two separate ears.

The Je Joue Rabbit Bullet’s traditional core is a pretty average bullet width (0.83 inches) – less precise than some famous bullets like the We-Vibe Tango X (0.69 inches).

If you use just one rabbit ear, you can limit contact to a smaller area if you’d like, but you can’t achieve firm pressure or strong vibrations doing this.

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 Je Joue Rabbit Bullet is easy to use and feels pleasant to hold. The handle is a comfortable length to grip and leverage, and the vibrations don’t travel much into your hand while using it.

However, applying firm pressure with the rabbit ears is difficult. They’re very flexible, and pressing firmly makes the vibrations feel weaker. Those who like to apply pressure would do better with a traditional bullet like the Je Joue Classic.

You can still achieve some pressure with the Je Joue Rabbit Bullet by pressing the rigid core against your body instead of the ears. But the ears can get in the way a bit when doing this.

The controls are excellent – the Je Joue Rabbit Bullet has separate buttons to increase and decrease power. A third button cycles through the vibration patterns. And you can adjust the intensity of each pattern. So you can quickly and easily find your preferred setting.

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 Je Joue Rabbit Bullet is disappointing during sex.

You need to place the rabbit ears precisely to feel the vibrations and situate them comfortably. This can be distracting and frustrating during sex.

Due to the flexible ears, firm pressure is also difficult to achieve with this bullet. Using the firm core at the base of the ears can help, but this requires holding the toy at an angle that starts to bump against your partner’s chest when facing each other.

Many bullets are easier to use during sex than the Je Joue Rabbit Bullet. I especially like options with a curved or angled head (like the Pillow Talk Racy and Lovense Ambi) that help the bullet fit more easily between bodies.

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 Je Joue Rabbit Bullet is exceptionally quiet. Even when I’m using the highest strength, my partner cannot hear this toy from the other side of a closed door. It’s a safe option if you live with others.

Of course, part of the reason it’s quiet is that it’s not very powerful. Plenty of stronger bullets are even quieter.

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 Je Joue Rabbit Bullet is rechargeable and has a reasonable battery life. In our test, it lasted 75 minutes on its highest power. This is enough for me, but it is slightly below average. You can find bullets that last over an hour and a half, like the We-Vibe Tango X.

If you choose the Je Joue Rabbit Bullet, just charge it after each use.

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 Je Joue Rabbit Bullet has excellent build quality. It has a good weight that makes it seem durable and feels nice in my hand. The silicone is silky smooth, and I enjoy the feel of the button press.

This seems like a solid bullet, and I’ve had no problems with it functioning as it should.

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 Je Joue Rabbit Bullet is 100% waterproof (IPX7), which makes it extremely easy to clean. You can fully submerge it in soapy water and scrub it without worrying about water damage.
