The FemmeFunn Booster Bullet is one of my strongest bullet vibrators and has a good range between low and high. 

I don’t consider many bullet vibrators’ top strength “extreme,” but the Booster Bullet is one I do. 

It reaches a 9.5 out of 10 on its top power level. I never need to use this setting because even the second level is intense. The Booster Bullet has about 5% more power than the cheaper FemmeFunn Ultra Bullet – though the Ultra’s 9 out of 10 top power is strong enough for most people. Depending on your budget, it might be worth saving the $20 going with the Ultra Bullet for the minimal difference.

There are better choices than the FemmeFunn Booster Bullet for those who need mild stimulation. Its lowest power is 4.75 out of 10 strength – it begins with a fair amount of power. If you need more gentle settings consider the Lovense Ambi or BMS Swan Maximum if you like buzzy vibrations. Or the We-Vibe Tango X if you prefer rumbly vibrations.

As someone who enjoys moderate to intense vibrations but nothing too extreme, I find the Booster Bullet’s starting level perfect as a warm-up. I spend a lot of time with it because you can vary how intense it feels by applying more or less pressure. Or by changing how direct the stimulation is on your clit.

Then, when I switch to the second power level, I’m ready for its strength and don’t find it overwhelming. This setting is around my ideal strength to finish.

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 rumbly vibrators higher than buzzy ones because it’s what most people prefer. But others prefer buzzy vibrators, so go with what you like! 

The FemmeFunn Booster Bullet is buzzy. Only the lowest power level is in the rumbly range. The two highest settings are moderately and extremely buzzy. This buzziness makes the already powerful vibrations feel even more intense.

I personally enjoy the Booster Bullet’s buzzy vibrations – it’s one of my favorites. But those who want deep, rumbly vibrations will want to go with the We-Vibe Tango X instead. It’s the most rumbly bullet I’ve tried. Although not quite as strong as the Booster Bullet, it will be enough strength for many people. 

Vibrations typically become buzzier the stronger they get. None of the bullets I’ve tested that have extreme strength like the FemmeFunn Booster Bullet are rumbly. So consider whether you value rumbliness or intensity more.

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.

The FemmeFunn Booster Bullet is neither broad nor particularly focused – it’s a happy medium. The relatively wide tip (nearly an inch) is broader than many bullets with a typical lipstick or tapered shape. And it’s rounded, making it feel broader too. This makes it comfortable for firm pressure because it’s more evenly distributing that weight instead of feeling pokey.

But it’s still narrower than several bullets and other mini vibrators like the We-Vibe Touch X. The tip is small enough to isolate vibrations to a reasonably small area, or you can use the side of the bullet to spread that out and cover a bit more space.

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 Booster Bullet is very comfortable, and the buttons provide good control.

The length is excellent for maneuvering without taking up too much space or cramping your fingers. The form is flexible, which makes it comfortable to press against your body. This flexibility means you need to shift your fingers and use them to press closer to the tip if you want extra-firm pressure rather than leveraging it from the base as you would with a rigid bullet.

The vibrations travel into your fingers a bit when using them to press near the tip (where the motor is located) for extra pressure, but it’s nothing too distracting.

You cycle through the 3 intensity levels and 17 patterns using a single button on the bullet’s base. This is less convenient than bullets that let you toggle forward and backward with separate buttons, like the We-Vibe Tango X. Still, the Booster Bullet is more advanced than other cycling bullets because of the Boost button and memory system.

The Boost button lets you quickly jump from wherever you are in the cycle to the top steady intensity level. So basically, whenever you’re on the edge, tap the Boost button to take you the rest of the way. In addition to the slight power increase, the Boost button is this bullet’s other upgrade over the FemmeFunn Ultra Bullet. If it doesn’t seem worthwhile to you, you can save some money and get the Ultra.

The Booster Bullet also has a built-in memory system (as does the Ultra Bullet). The next time you use the bullet, it will pick up at your most recent setting. That way, if you have a favorite setting, you won’t need to cycle through all the patterns to find it again. 

And for those who prefer warming up on the gentlest setting, the next click of the button will take you directly to the lowest constant power level.

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.

This bullet works amazingly well during sex. It’s a great size to slip into tight spaces without taking up much room or bumping against your partner. Its round tip and flexible form make it especially comfortable, even with heavy movement during sex. It flexes with your body to remain in comfortable contact with your clit (directly or indirectly). 

It’s also a reasonably long bullet, so I don’t need to keep my hands too far down during sex.

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 Booster Bullet has good, quiet noise levels. Our decibel readings were lower than the average bullet – this is especially impressive considering it’s one of the most powerful I’ve tested.

We also test whether someone would hear the bullet on the other side of a closed door. My partner stands directly on the other side of the door while I use the bullet in the bedroom.

The first two power levels were completely inaudible, but my partner could just barely hear it on the highest setting. This is the note he left in our testing spreadsheet word for word:

“This was just barely perceptible on high. I had to try really hard and wait for sounds outside to become extremely quiet. I doubt anyone would actually hear in typical use.”

Turning on a box fan or music solves this problem completely, so you can use this to mask the noise if you want to use all power levels.

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 Booster Bullet is rechargeable and lasted 85 minutes on high power during our testing. It has the longest battery life of my “extremely powerful” bullets. And if you also use the lower or middle powers occasionally, you’ll prolong the lifespan even more.

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.

The FemmeFunn Booster Bullet has excellent build quality. The body-safe silicone is smooth and comfortable. The ABS Plastic housing the motor also feels solid. It has some good weight, making it feel more durable than cheap, lightweight bullets. The silicone buttons also feel well-made. 

The flexible part is a little squeaky, which is not as luxurious as I would hope, but it hasn’t caused me any issues. I’m comfortable applying firm pressure without worrying about damaging the bullet.

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.

Since the Booster Bullet is entirely waterproof, it’s very easy to clean. You can completely submerge it while scrubbing it with soap and water. No worrying about damaging the toy.

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.
