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 Tango has an excellent power range. It’s a great option for someone wanting soft, moderate, and intense power levels in one bullet.

The We-Vibe Tango begins with 2.5 out of 10 vibration strength, which provides an excellent warm-up. Low levels like this are useful in the beginning to prevent overstimulation. And some people prefer mild vibrations the entire time. The two middle levels are moderately powerful, with reasonably gradual steps between intensities.

Then, the top strength reaches 7.75 out of 10 vibration strength. This is plenty of power for me to orgasm with, though I typically use the top strength and am glad it’s not any less powerful. The highest setting is not so intense that it feels overwhelming to me.

If you enjoy extreme power, there are some stronger bullet vibrators like the Blush Limited Addiction or FemmeFunn Ultra Bullet. Each has a top power level that is too intense for me personally, but they lack gentle settings.

The We-Vibe Tango’s 4 power settings provide a great variety to ensure you find a comfortable and stimulating level. It will satisfy all except those who need extreme power.

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 deep, low-frequency vibrations.

The We-Vibe Tango is incredibly rumbly. Of all the bullet vibrators I’ve tested, only the upgraded We-Vibe Tango X is more rumbly. The Tango’s first 3 power levels are extremely rumbly. Its rumbliness is especially impressive considering its strength – vibrators always become buzzier as you increase power. But even the Tango’s highest strength remains moderately rumbly.

Powerful, deep vibrations typically come with a high price tag. But since the Tango is no longer in production and is being sold at a discount, it’s currently the most affordable rumbly bullet.

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 Tango is best for those who prefer precise stimulation because of its thin (0.67 inches) lipstick-shaped tip. This design covers a small area, so it’s great at hitting a specific spot without affecting other areas where you don’t want vibrations much.

You can achieve a bit broader coverage by pressing the Tango’s side to your body to spread the vibrations out more. But it’s easiest to use for focused 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 We-Vibe Tango is comfortable and easy to use. The thin, firm core makes it easy to maneuver and leverage to hit your desired spot.

The vibrations don’t travel much into my hand while I’m using it, so it’s very comfortable to grip.

You control the Tango with a single button on the toy’s base. You’ll cycle through the 4 power settings and 4 patterns. I prefer the multi-button system of the updated We-Vibe Tango X, which lets you increase or decrease power instead of cycling through levels. But if you don’t want to spend the extra money to upgrade, the Tango’s cycle setup just takes some getting used to.

At most, you’re 8 clicks away from your desired setting since there are only a few intensity levels and patterns. And the button placement is ideal –  I don’t have to adjust my natural grip on the bullet to press the button.

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 Tango is great during sex. The rumbly vibrations travel deeper into your body and affect a wider area, which is helpful so that you don’t have to pay much attention to precisely positioning the bullet. I find these rumbly vibrations enhance sex without feeling overstimulating.

The thin design allows the Tango to slip into tight spaces easily and helps me keep good contact with my body. The original Tango is a half-inch shorter than the We-Vibe Tango X. The shorter length makes it a bit more challenging to grip during sex than the newer model. You have to pinch the end to hold it, but it’s still pretty easy.

The We-Vibe Tango is a good, affordable option if you want a bullet to use frequently during sex.

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 Tango has passable noise levels, but there are quieter bullet vibrators.

When the Tango is not pressed against your body, it can sometimes make a rattling sound. On the two highest levels, if I don’t keep the bullet pressed to my skin, my partner can hear the rattle from the other side of the bedroom door.

Turning on a box fan or playing music masks this noise entirely. So, if you live with others, you’ll want to keep the bullet in contact with your body or add background noise to cover the sound.

If noise is a big concern to you, the Pillow Talk Racy covers a similar power range but is inaudible behind a closed door on all settings.

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 Tango is rechargeable and has a great battery life. During our tests, it lasted 95 minutes, continuously vibrating on high power. This is more than most people will use in a session, and I can enjoy it multiple times without charging between uses.

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 Tango has a simple but great build quality. I love how the weight falls towards the tip, and it’s a comfortable amount of weight that gives it a sturdy and luxurious feel. The ABS Plastic construction does not feel too lightweight or cheap. I can apply solid pressure without feeling like I’ll damage the Tango.

It’s less luxurious than the new We-Vibe Tango X, which has a more comfortable silicone handle.

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.
