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 Nasstoys Intense Travel Vibe Mini lives up to its name because its power levels are all strong – especially for such a small, affordable bullet vibrator. The starting point is already a 6 out of 10 vibration strength, and the top power reaches an 8.75 out of 10.

I can orgasm using just its first setting, which is comparable to the strength of many mid-sized vibrators. And the 3 settings it has are enough to provide comfortable, gradual steps between levels since its power range is relatively narrow.

If you like intensity, it’s excellent. But if you need mild warmups or prefer softer settings, this bullet vibrator may be too strong for you. In this price range, consider the Pillow Talk Flirty if you prefer mild stimulation. Or consider the Blush Limited Addiction if you want intense top settings but need just a touch less intensity on low. Bullet vibrators with much wider power ranges, providing very gentle and intense settings, are pricier.

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 most people prefer them. However, plenty of people enjoy buzzy vibrations more.

The Nasstoys Travel Vibe Mini is much better suited for those who like neutral or buzzy vibrations (like me). It has no rumbly settings. The lowest level is neutral, the middle is moderately buzzy, and the most intense setting feels extremely buzzy.

These buzzy vibrations have more of an impact at the surface which can make them feel more intense. Some people will find that overstimulating, but others will love it.

If you prefer low-frequency, rumbly vibrations, you’ll have to increase your budget. The most affordable rumbly option is the Pillow Talk Racy. Or for exceptional rumbliness the We-Vibe Tango X is best. But in general, the most rumbly bullet vibrators I’ve tested are less intense than the Nasstoys Intense Travel Vibe Mini. So, decide based on which you care more about.

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.

Like most bullets, the Nasstoys Intense Travel Vibe Mini provides more focused stimulation than other kinds of vibrators. Compared to other bullets, the amount of precision is toward the middle of the spectrum.

The Intense Travel Vibe Mini is 0.83 inches wide where the tip begins to taper – this feels focused but certainly not pinpoint. By pressing the side of the bullet to your body, you can get comfortable, firm pressure that’s not too precise. Or, if you prefer more pinpoint precision, the tip is tapered – so you can press the top of the bullet to limit the contact to a small area. This can be great if you like direct clitoral stimulation.

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 Nasstoys Intense Travel Vibe Mini is comfortable and easy to use.

Its 3.8-inch length is long enough to easily leverage without tiring your fingers or wrist. Although the vibrations travel into my hand some, they’re less noticeable once I press the bullet against my body. I don’t find them distracting.

The button is easy to press without changing your grip, but it’s a one-button control system. This means you have to cycle through the 3 power levels and 7 patterns on a loop – there’s no separate button to decrease power.

But I appreciate that turning the bullet off and back on resets the vibrator to its softest power. It’s an easy workaround to quickly decrease the intensity.

If you value having separate controls to increase and decrease power, the Blush Limited Addiction is the best option at this price point.

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 Nasstoys Travel Vibe works great during sex!

It’s a great length to leverage. Alghough it’s a straight bullet, so you don’t get the additional help that a curved shape (like the Pillow Talk Racy) provides. The width of the head is small enough to fit in tight areas yet large enough to hit the right spots comfortably.

I can angle the bullet vibe well without the base bumping into my partner’s chest in positions where we’re facing each other. And the tapered tip maintains really good contact with my clit – I can easily get direct clit stimulation during sex.

If you are looking for a bullet that works well to stimulate during sex, the Nasstoys Intense Travel Vibe Mini is one of the best at this price.

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 Nasstoys bullet is very discreet, especially for its power.

During our testing, I could use every power level without my partner hearing the vibrations from the other side of our closed bedroom door. So there’s no concern if you live with housemates.

We measured its top intensity level at 46.1 decibels – lower than most bullet vibrators with this much strength.

As someone who can be a little sensitive to noises in general, I don’t find the sound of its vibrations annoying or distracting at all. It’s a powerful, discreet bullet vibrator.

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 Nasstoys Travel Vibe is rechargeable and has one of the longest-lasting batteries of the bullets we’ve tested. During our test, it lasted 105 minutes at maximum power. It’s challenging to find one this strong that lasts this long.

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 Nasstoys Intense Travel Vibe Mini feels well-made, and I’ve had only good, reliable experiences with it. It has a nice weight that makes it feel solid, especially compared to other budget bullet vibrators. And the body-safe ABS plastic material is very smooth and comfortable. I like the feel of the button too.

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.

This bullet is IPX7 waterproof, which makes cleaning very easy. You can fully submerge it while scrubbing without worrying about water causing damage.
