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 We-Vibe Touch X has an excellent power range with soft, moderate, and strong settings. Its top power is a 7.75 out of 10 vibration strength. While not as extreme as some, it’s more than enough power for most people.

The Touch X’s gentlest setting is just 1.5 out of 10 vibration strength, so it begins softly enough for those overstimulated by intensity or who need a warmup. And it climbs gradually through its 8 power levels. There are no large, uncomfortable leaps. Since it thoroughly covers the soft, moderate, and powerful ranges, you’ll likely find vibration levels you enjoy – regardless of whether you prefer mild or powerful stimulation.

I enjoy each power level and usually orgasm on one of the top two settings. Its highest strength of 7.75 is effective without feeling overwhelming. I typically don’t use the higher settings of my stronger bullet and mini vibrators because I find power levels above 9 too intense.

Consider the FemmeFunn Booster Bullet or Blush Limited Addiction if you prefer extreme intensity. However, none of the extremely powerful bullet or mini vibrators I’ve tested have gentle warmup levels (or rumbly vibrations like the Touch X). The Touch X’s more comprehensive power range is better for most people.

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.

The We-Vibe Touch X has great rumbliness. The first 5 power levels are rumbly and provide that resonant, impactful stimulation that travels deeper than buzzy vibes. I love that the starting powers are so low-frequency because they feel gentle on the surface, so my clit is not overstimulated. But they travel deep and warm up my body for more intense vibrations.

And the Touch never becomes buzzy – even on its max power. The top 3 settings are neutral (neither rumbly nor buzzy). This adds a kick to those higher power levels that you feel more at the surface of your clit. I love neutral vibrations at this strength. It’s part of why the Touch X is one of my favorite mini vibrators. But if extreme rumbliness is your top priority, the We-Vibe Tango X is even more rumbly.

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.

The We-Vibe Touch X provides broad stimulation. This widespread contact is great if you want direct clitoral stimulation, but you’re also prone to overstimulation. This broad surface area is the only way I can enjoy direct clitoral vibrations because the pressure is more diffuse.

This rumbly vibrator blankets your vulva with soft, smooth silicone. The firm core of this toy allows you to apply some pressure over a wider area. Or you can use the flexible tip to target a more precise spot comfortably.

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 We-Vibe Touch X is very comfortable and easy to use. The wide, flat design fits comfortably in my hand, and I can easily push it against my vulva with my palm. Even though it has more contact with my hand than bullet-shaped toys, the vibrations only travel minimally into my hand since the plush silicone dampens them. So it’s very comfortable to hold.

As a palm vibrator, there’s not an obvious handle as bullet or wand vibrators have. So leveraging the Touch X for heavy pressure is less intuitive. You may need to adjust your finger placement or grip on the vibrator to apply substantial pressure. Those who enjoy especially firm pressure may consider a mini wand vibrator like the Magic Wand Mini. 

But I enjoy gentle to medium pressure with the Touch X’s broad contact area – and this is easy to apply with your palm.

The Touch X’s buttons provide fantastic control. It has 3 buttons to increase and decrease power or move through its 6 vibration patterns. So you can quickly reach your preferred setting. This is much more convenient than the one-button system most mini and bullet vibrators use, which requires you to cycle through every intensity level and pattern to return to a previous setting. This is another way the Touch X improved on the old model.

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 We-Vibe Touch X is awesome to use during sex. 

The Touch X’s tip is thin and curves downward slightly. And although its shape is relatively wide, it’s also contoured and reasonably flat. These aspects help it slip easily into tight spaces despite being bigger than many bullet vibrators. It maintains excellent contact with my clit, even in positions where space is limited, like Missionary.

It presses comfortably on my body, and the rumbly vibrations travel deep to stimulate me well. With a classic-shaped bullet vibrator, I spend more time trying to find a comfortable and effective placement. But the broader, flat surface of the Touch X blankets everything and eliminates the need to find the exact right spot.

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 We-Vibe Touch X is exceptionally discreet. It’s one of my quietest vibrators, which is especially impressive considering its high power.

My partner cannot hear it from the other side of the bedroom door when I’m using it on any power level or setting. And even from within the room, the sound is so subtle that even the most noise-sensitive folks will find this one hardly detectable.

When measuring noise, the We-Vibe Touch X was one of the only bullets or mini vibrators that was too quiet for our Sound Level Meter to measure. On its highest power, the Touch X remained quieter than the ambient background noise of the room itself. So, the 35 dB listed above is the ambient room noise. To measure the actual decibels, we will need a quieter testing studio.

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 We-Vibe Touch X is rechargeable and has a good battery life, lasting 85 minutes on high power during our testing. This is plenty for me, and I typically use it several times without charging between uses.

It uses We-Vibe’s standard magnetic USB charging cable, which is the same across almost all their current products.

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 We-Vibe Touch X has superb build quality. It’s covered entirely in silky smooth silicone. The silicone is thicker and more plush than other vibrators, especially near the tip. This makes it feel especially comfortable and luxurious. It still has a solid, rigid body beneath the silicone with a good weight that feels sturdy and durable. The buttons are also easy to press and feel well-made.

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 We-Vibe Touch X is 100% waterproof, making it very easy to clean. You can submerge this toy completely while you scrub it with soap and water! And, of course, you can use it in the bathtub or shower.
