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 Lelo Mia 2 has a very soft power range, which can be good or bad depending on your needs. Its first power starts at 0.1 out of 10 for vibration strength, which is the gentlest of all my bullet vibrators. There are 12 power settings in total, with the top strength reaching only 3.25 out of 10.

This means you have lots of small, incremental power steps to enjoy within that gentle range. Making the Mia 2 a nice option for those who are easily overstimulated and who need lots of soft vibrations without too much intensity. I can orgasm with the top strength of the Mia 2, but it definitely takes some effort.

I like more power personally, and those who want intensity will prefer other options in a comparable price range. For instance, the Lovense Ambi and We-Vibe Touch X each reach closer to an 8 out of 10 on high and begin softly at 1.5 and 2.5 out of 10 on low. So you still have gentler strengths for warming up, but you also have the option to crank up the intensity.

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 it’s what most people prefer. 

The Lelo Mia 2 has average rumbliness. The low powers are in the rumbly range, but the higher strengths are in the neutral range. Since it has low overall strength, those neutral-feeling higher powers are the ones you’ll likely use most often.

Personal preferences on vibration frequency vary, and I actually really enjoy the Lelo Mia’s neutral vibrations. But if you want the most rumbly option you can find, the We-Vibe Tango X is a great alternative in the same price range.

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.

The Lelo Mia 2 provides a medium amount of precision (purely a personal preference) compared to other bullet and mini vibrators – a hybrid between broad and focused. It has a relatively narrow, rounded tip that provides fairly focused stimulation. But the tip does not come to a fine point like many tapered or lipstick-shaped bullets that provide very precise stimulation.

Likewise, some mini vibrators like the We-Vibe Touch X provide broader stimulation that blankets more of your vulva. But still, you can get somewhat broad stimulation from the Mia 2 by angling it and pressing the side of the bullet against you rather than the tip.

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 Lelo Mia 2 is very comfortable. The Mia is longer than most bullets and has a firm texture making it very easy to grip and leverage for solid pressure.

The Mia has separate buttons to increase and decrease vibration power. This is helpful over the one-button system many bullet vibrators use that requires you to cycle through levels. The buttons take firmer pressure than some, but this means you don’t accidentally adjust the power when you don’t mean to.

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 Lelo Mia 2 is easy to use and effective during sex. The thin design makes it easy to fit into tight spaces. I can easily move the Mia around without the end hitting my partner’s chest.

It’s made of very firm plastic, which can bump around a bit in missionary or other positions where your partner may occasionally press the toy against you. It’s small enough that it does not cause discomfort, but if you’d prefer something more plush, the Dame Pom is very squishy and flexible. But I think most people will not be bothered by the firmness of the Mia’s tip.

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 Lelo Mia 2 is one of my quietest bullets and cannot be heard from behind a closed door at all. But this is primarily because it’s a low-powered bullet vibrator that’s best for those who need gentle vibrations.

If you prefer intense vibrations, there are more powerful bullet and mini vibrators that are also discreet. The We-Vibe Touch X and Lovense Ambi are two much stronger options that are also entirely inaudible behind a closed door.

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 Lelo Mia 2 is rechargeable and lasts for an hour and a half on its highest power. This is long for a bullet. However, since its max setting is actually quite gentle, the battery life isn’t too impressive since it doesn’t use much power.

If you want more powerful bullets that last about the same time on their highest power, the We-Vibe Tango X and We-Vibe Touch X are excellent options. They’ll last even longer if you also tend to use some gentle settings part of the time.

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 Lelo Mia 2 has a decent build quality. I haven’t experienced any issues with it, but its extremely lightweight plastic construction feels somewhat cheap. The buttons also take some firm pressure to press. It just doesn’t feel as luxurious as some other premium bullet vibrators.

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.

The Lelo Mia 2 is completely IPX7 waterproof, which makes it very easy to clean. You can completely submerge it in water while you’re scrubbing with soap and water – absolutely no worries.
