The FemmeFunn Ultra Bullet is one of the most powerful bullet vibrators I’ve tested. It has a good range for those who prefer mid-strength to extreme vibration power.

The lowest level starts at a 4.5 out of 10 vibration strength. This power is effective yet gentle enough that it doesn’t feel overstimulating. It’s a versatile mid-strength setting I can comfortably enjoy as a warmup. Or I can make it feel more intense by adjusting my pressure. Many high-powered bullet vibrators like this do not have a soft enough starting level, so I appreciate this about the FemmeFunn Ultra Bullet.

If you need especially gentle warmup levels, consider the BMS Swan Maximum or Pillow Talk Racy. But most people will find the Ultra Bullet’s starting level comfortable.

The second power level hits an 8 out of 10 vibration strength, which is quite a jump – nearly twice as strong. But after I spend some time warming up on that first power level, I’m ready for the intense second setting. 

The FemmeFunn Ultra Bullet’s final intensity level reaches 9 out of 10 vibration strength, which I consider extreme. Only a couple bullets, like the BMS Swan Maximum, reach a more intense strength, but few people will want more power. I rarely even use the FemmeFunn Ultra Bullet’s top setting (I typically finish on the second level), but power queens will love it.

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 vibrations that are rumbly higher than those that are buzzy because it’s what most people prefer. However, others prefer buzzy vibrations, so consider what you enjoy!

The FemmeFunn Ultra Bullet only has passable rumbliness because just the first power setting is in the rumbly range. The two higher powers are buzzy. I personally enjoy moderately buzzy vibrations – especially in a bullet vibrator. So I love the FemmeFunn Ultra Bullet. It’s all based on your personal preference.

Powerful, buzzy vibrations tend to feel especially intense. So, if you’re unsure whether you prefer rumbly or buzzy but know that you like intensity, this could be the perfect choice! 

If you enjoy rumbly vibrations more, you’ll prefer the We-Vibe Tango X, though it is a bit more expensive. If the cheaper original We-Vibe Tango is available, snatch that up because it’s no longer in production but is the most affordable bullet with powerful, rumbly vibrations.

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.

Whether you enjoy pinpoint or broad stimulation is entirely a personal preference.

The FemmeFunn Ultra Bullet is between broad and focused stimulation. Its tip is nearly an inch wide, which is broader than most bullets with lipstick-shaped or tapered tips (like the We-Vibe Tango X or Nasstoys Intense Travel Vibe Mini). However, it’s more focused than palm vibrators like the We-Vibe Touch X or Dame Pom.

The FemmeFunn Ultra Bullet also has a rounded tip, making it feel slightly broader than a typical bullet. This is useful and comfortable if you prefer firm pressure because it’s less pokey than pointed tips. You can also use the side of the bullet to disperse the vibrations a bit.

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 Ultra Bullet is very comfortable and fairly easy to adjust the settings. The flexible core makes the pressure against your body feel plush despite its firm tip. And even though the form is not rigid, it’s easy to slide a finger near the tip to apply more pressure.

If you use your fingers near the motor, the vibrations travel into your fingers, but it’s not distracting unless you’re particularly sensitive to this. The Ultra Bullet’s comfortable width and above-average length make it easy to grip and maneuver wherever you want.

The FemmeFunn Ultra Bullet uses one button to cycle through the 3 intensity levels and all 17 vibration patterns. I prefer toys with separate controls to move forward and backward through settings. But the Ultra Bullet’s one-button system is much more user-friendly than most one-button bullet vibrators. Here’s why:

The FemmeFunn Ultra Bullet has a memory system. This means if you turn the toy off after using a pulsing pattern, it will start again on that pulsing pattern when you turn it back on. That way, you don’t have to tap the button 10+ times to return to your favorite setting.

But it also makes it easy to return to the softest steady vibration. After turning the toy on and automatically returning to the most recently used setting, the next button click will bring you back to the lowest power level. 

This makes it easy to return to my warmup intensity when necessary. Then, I can work my way back up. So it’s set up with the natural rhythm your body wants to take and saves you from another slew of taps to get back around to the start again. 

It’s still not as convenient as bullets with separate buttons to change power and move through patterns, like the We-Vibe Tango X. But the FemmeFunn Ultra Bullet’s unique system makes it much better than other one-button cycling bullets I’ve tried.

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.

The FemmeFunn Ultra Bullet is fantastic during sex. It’s a great size to leverage without bumping into your partner and fits easily into tight spaces. 

The flexible form is beneficial when there’s a lot of movement because it moves along with your body instead of bumping against your pubic bone. So it stays comfortably in contact with your clit, providing excellent stimulation.

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 Ultra Bullet is reasonably quiet. The decibel measurements we recorded for the FemmeFunn Ultra Bullet were softer than average. 

We also test whether someone on the other side of a closed bedroom door can hear the vibrator. My partner could not hear the FemmeFunn Ultra Bullet on low or medium strength. On its highest setting, my partner thought he could barely hear it. But this was his note: “I had to listen very closely and wait for any sounds outside to become extremely quiet. Even then, I could just barely make it out occasionally. I doubt anyone would actually hear it in normal use.” 

Considering it’s one of the most powerful bullet vibrators I’ve tested, the Ultra Bullet’s noise performance is pretty good. And to be safe, you can turn on a box fan or play music in the bedroom to ensure no one will hear it.

I’m also pretty sensitive to noise, and the Ultra Bullet’s sound doesn’t bother me at all. So, it’s a safe option if you’re distracted by sound.

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 Ultra Bullet is rechargeable and lasted 85 minutes, constantly vibrating on high power during our testing. This is great for a bullet of this immense strength. I frequently forget to charge between uses, and it still has plenty of remaining battery.

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.

This bullet has a great build quality. The body-safe silicone is smooth yet has a slight, comfortable grippiness to it that I enjoy. The ABS plastic frame beneath the silicone feels solid. The flexible areas feel a little squeaky but seem sturdy, and I’m not afraid they’ll break when I’m applying pressure.

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.

This FemmeFunn Ultra Bullet is IPX7 waterproof. This means you can completely submerge it, making it easy to clean. Just wash in the sink with soap and warm water.

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