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 VeDO Bam is a powerful bullet with no low or medium power levels. If you prefer intensity, it’s enjoyable! But its lowest of 3 settings is a 7.9 out of 10 for strength, so it can be jarring if you don’t start by warming up with a gentler bullet first.

It reaches a 9.5 out of 10 on high, one of the most powerful I’ve tested. However, the Bam’s power and range underperform compared to cheaper options. The Blush Limited Addiction begins softer (5 out of 10) than the VeDO Bam and finishes stronger (10 out of 10) at a cheaper price. On the other hand, if you prefer milder stimulation, try the Pillow Talk Flirty instead – a bullet with its power range focused around gentler settings.

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 want. But this is a personal preference, so if you enjoy buzzy vibes, pay more attention to the frequency chart than the rating.

The VeDO Bam’s vibrations have a neutral feeling on its lowest two settings, and its highest setting is moderately buzzy. I personally enjoy the first two powers because I like neutral vibrations in a bullet. They provide a bit of zing while still traveling reasonably deep. But it would be nice if the VeDO Bam also had some rumbly low levels like the Blush Limited Addiction has. 

You’ll need to increase your budget if you care a lot about having deep, rumbly vibrations. Most bullet vibrators in the VeDO Bam’s price range have decent, but not excellent, rumbliness. The Pillow Talk Racy is a bit more expensive, and two-thirds of its power range is 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.

You can get a mix of focused and broad stimulation from the VeDO Bam. It’s wider than many bullet vibrators, so you can get somewhat broad stimulation and pressure using the side of the bullet. But the tip has a slight taper, so you can use the end for more precise stimulation. As a result, it’s pretty versatile.

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 VeDO Bam is a comfortable and easy-to-use bullet vibrator. It’s a great length for leveraging, and since the structure is very rigid, you can get excellent pressure.

The VeDO Bam transfers some slight vibrations into your hand. But it will only bother people especially sensitive to this. 

The button to control the vibration intensity and patterns is on the bottom. You have to adjust your grip slightly during use to press the button. You must also cycle through all powers and patterns to get to the one you want. It starts on the highest strength and cycles down to lower powers as you keep pressing. And since there are 3 power levels and 7 vibration patterns, there’s a lot to tap through.

I prefer bullets that let me power up or back down to find my ideal setting. That way, if I miss the one I want, I don’t have to cycle back through everything again. The Blush Limited Addiction is a budget-friendly option with a multi-button system.

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 VeDO Bam is a great size and shape for getting into tight spaces and leveraging easily during sex. 

The vibrations travel into the handle a little bit, which does not bother me much during solo use but can be distracting during sex for some. It’s all about how I hold the bullet, and I find it less distracting in the spooning position than in missionary.

I don’t notice handle vibrations as much with the Blush Limited Addiction, Pillow Talk Flirty, or Pillow Talk Racy. The Racy even has a convenient inward curve, useful for leveraging the bullet without bumping against your partner. And since they’re about the same price and are better overall, I’d recommend one of these instead of the VeDO Bam if you want something great 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 VeDO Bam is inaudible behind a closed door on all intensity levels – even with its exceptional power. So it’s a safe option if you are worried about housemates overhearing. 

The vibrations have a buzzy pitch, which isn’t as pleasant as deeper-sounding bullets, but they don’t bother me because they’re relatively quiet. If you are very noise-sensitive, there are quieter, deeper-sounding bullet and mini vibrators like the We-Vibe Touch X or Je Joue Classic.

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 VeDO Bam is rechargeable and lasted 78 minutes, continuously vibrating on high power during our testing. This is impressive, considering the bullet’s high strength.

You can find other high-powered options that last over an hour but are typically more expensive. So this is a great budget-friendly option if you care about a long runtime.

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 VeDO Bam has a good build quality. It has a nice weight that makes it feel solid and well-made. You charge the bullet by screwing off a plastic cap, which makes it feel a little cheaper. But the silicone is smooth and comfortable. It’s not quite as luxurious as some models, but it looks good, and I’ve had no issues with it.

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 VeDO Bam is completely waterproof, so it’s very easy to clean. It has an IPX7 rating which means you can safely submerge it up to a meter deep for up to half an hour. So simply clean it with soap and water.
