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 Maude Vibe has great strength and decent range. It’s best if you prefer moderate to intense vibrations and don’t need many gentle settings. It starts at a 5 out of 10 on the lowest level and reaches 8 out of 10 on the highest. With 3 power levels, jumps between settings aren’t staggering, but they’re not gradual either.

With how buzzy the vibrations are, even the first power level feels pretty intense and can bring me to orgasm, so I often don’t go up to the second power. I enjoy the Maude Vibe, but since there are no truly gentle levels, I’ll sometimes use another vibrator to warm up.

If you enjoy moderate to intense power but need gentler levels when warming up, you could also consider the Lovense Ambi or BMS Swan Maximum Bullet. Each reaches at least the same intensity as the Maude Vibe, but they both have gentler settings too.

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 toys with rumbly vibrations higher than those with buzzy ones because it’s what most people prefer. But it’s a preference that varies from person to person, and I actually enjoy several neutral or moderately-buzzy bullet vibrators myself.

The Maude Vibe is primarily a buzzy bullet vibrator. Its first intensity level feels neutral (not quite buzzy yet), but its second feels moderately buzzy, and the third is extremely buzzy. I really enjoy the Maude Vibe’s first level and use it often. Though personally, I find its upper settings a bit too buzzy combined with their intense strength.

I think the Maude Vibe is a great option if you want an intense, buzzy bullet vibrator. Those who prefer rumbliness will want to consider the Je Joue Classic in a similar price range or the We-Vibe Tango X (my most rumbly bullet) if you have a larger budget.

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 Maude Vibe provides a medium amount of precision compared to other bullets and mini vibrators. It’s definitely not broad like palm vibrators such as the Dame Pom or We-Vibe Touch X. But its rounded tip doesn’t come to a fine, precise point like tapered-tipped or lipstick-shaped bullets.

It’s reasonably versatile as you can use just the end for more focused stimulation or press its widened side against your vulva to cover more surface area.

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 Maude Vibe is reasonably comfortable and easy to use. It’s a great length to leverage for firm pressure, and its tapered shape helps it fit easily in tight spots. The vibes travel minimally into my hand, but I don’t find it distracting. Unless that’s an area you’re especially sensitive to, it won’t be a deal-breaker for most people.

It has a one-button control system to cycle through the 3 power levels. Since there are only a few levels and no vibration patterns, I don’t mind that you need to cycle through the settings to step back down in intensity. But I have noticed some responsiveness issues with the button. Sometimes I have to press it a couple of times before it works.

If you strongly prefer the ability to increase and decrease power with separate buttons, the Je Joue Classic and We-Vibe Tango X are great choices. These two also have the most similar power range to the Maude Vibe, but they are more rumbly.

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 Maude Vibe is generally good to use during sex. It works best in positions where you’re not facing your partner (like Spooning or Doggystyle). It fits into tight spaces, and you can leverage it comfortably with just one hand. Its rounded tip and shape that widens toward the base also help it maintain excellent contact with my clit during movement.

The Maude Vibe is a little trickier in positions where you are facing your partner, like Missionary. Since the Maude Vibe is longer than some bullets, the handle can bump against your partner. But if you angle it differently, you can still achieve good clit stimulation without issue. I still generally enjoy it in all positions.

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 Maude Vibe is discreet. In our testing, it was inaudible on all power levels from behind a closed door. So it’s safe for those worried about roommates overhearing or just general discretion.

I also don’t find the sound annoying or distracting at all during solo or partnered play.

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 Maude Vibe is rechargeable and lasts for just under an hour on high power. This is below average for a bullet, but will still be good enough for most people. Since I mostly use its lower power level, I can extend the runtime and get a couple uses in before charging.

If you care strongly about battery life a few of our bullets last over an hour and a half, including the We-Vibe Tango X and Nasstoys Intense Travel Vibe Mini.

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 Maude Vibe has a decent build quality. It’s completely covered in a comfortable smooth silicone, which I love. And it has a slightly flexible tip with a little bit of squish to it. The feel and unique shape are luxurious.

My only complaint is the button, which you must press fairly hard, and sometimes it takes a couple of tries to get it turned on because it has some responsiveness issues. It’s something you get used to if you’re using it often, but could be frustrating to some.

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 Maude Vibe is very easy to clean. It has an IPX6 water-resistance rating which means it can safely resist heavy jet-streams of water. So you can safely clean it with soap and water under a running faucet. But you should not completely submerge it.
