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 We-Vibe Tango X has an excellent power range that provides gentle, moderate, and strong power levels. It begins with 2.5 out of 10 vibration strength. The comfortable soft settings are great while warming up or for those overstimulated by intensity. 

The upper power levels are strong, reaching a 7.75 out of 10 strength. I easily orgasm with the Tango X but typically use its top setting. There are some with more extreme power, like the FemmeFunn Booster Bullet or BMS Swan Maximum Bullet, for those who crave immense intensity. But I don’t personally need more strength than the Tango X provides.

The Tango X has improved on the original We-Vibe Tango in that it has 8 power levels instead of 4. So, the new model covers its power range more completely with many gradual steps between intensity levels. You can work up to its top power very slowly. Or if you’re easily overstimulated, you have many gentle or moderate power levels to enjoy. 

Most people will enjoy the We-Vibe Tango X’s vibrations. Few bullets have as wide a range of power as this one.

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.

The We-Vibe Tango X is the most rumbly bullet vibrator I own. This is one of the main reasons to consider this bullet. 

Its rumbliness is especially impressive considering the Tango X’s strength. Vibrators become buzzier as you increase power. But even its top setting (7.75 out of 10 power) measured at 58 Hz in our test results, which is extremely rumbly. No other bullet besides the Tango X and Tango had more than 5.0 vibration strength while remaining under 60 Hz (our threshold for the “extremely rumbly” range).

Now, rumbliness vs buzziness is a personal preference. Although most people prefer rumbly vibrations, some want neutral or even buzzy vibes. If that’s you, consider the Pillow Talk Racy if you like neutral vibrations or the Lovense Ambi for moderately buzzy vibrations.

The We-Vibe Tango X is the best if you’re like most people and want those deep-feeling, rumbly vibrations. If you enjoy larger toys with more extreme power, you could also consider the We-Vibe Wand 2 – one of my best wand vibrators with exceptionally rumbly vibrations.

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 We-Vibe Tango X provides focused stimulation due to its thin width (0.69 inches) and lipstick-shaped tip. The lipstick tip comes to a fine edge that you can use to target the vibrations into an exact area. 

Rumbly vibrations travel deep into the body and feel like they naturally impact a more significant area, so limiting the contact to a particular spot is nice.

If you want slightly broader stimulation, you can use the long side of the Tango X to spread out the contact area more.

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 We-Vibe Tango X is an exceptionally comfortable and easy-to-use bullet. 

It has better controls than other bullet vibrators. Unlike most bullets, which offer a single button to cycle through all the intensity levels and patterns, the Tango X has separate buttons to increase and decrease power; and a third button to move through its vibration patterns. 

The three buttons allow you to quickly access your desired intensity or pattern and avoid annoying disruptions searching for your favorite power level.

The rigid form makes it easy to leverage and apply pressure even with its average length. I love the silicone grip on the handle, and the vibrations do not travel much into my hand, so it’s very comfortable.

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 We-Vibe Tango X is awesome during sex! The rumbly vibrations travel deep into your body, so you don’t have to worry about placing the bullet in a precise spot. The thin, focused tip lets you easily slip the Tango X into tight spaces, and it maintains good contact wherever you place it.

I like that the Tango X is a bit longer than the original Tango because it makes for a more comfortable grip. You don’t need to pinch the end with your fingers; the handle has more space to sit comfortably in your hand so you can leverage the Tango X more easily. 

This length also helps to limit how far you have to reach during sex. But it’s not so long that it bumps against my partner’s chest or gets in the way.

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 We-Vibe Tango X’s noise performance is mediocre and may be disappointing if you’re especially worried about discretion. But there are ways to make it completely unnoticeable.

When measuring the Tango X’s noise with a Sound Level Meter, the Tango X’s vibrations measured quieter than the average bullet vibrator. However, when I hold the Tango X loosely in my hand, it will occasionally make a rattling sound that my partner can hear while standing on the other side of our closed bedroom door. 

When you press the Tango X to your body or grip the bullet more firmly, the rattling does not happen. And the rumbly vibrations themselves are inaudible from the other side of the closed door. If you don’t want to be distracted focusing on keeping the Tango X pressed to your body, you can turn a box fan on or play music in the bedroom. Both options successfully masked the rattling sound so my partner could not hear it outside the bedroom. 

The We-Vibe Touch X is my quietest mini-vibrator if you’d like a more discreet option. Otherwise, the Tango X just takes a little creativity to prevent nosey housemates from hearing.

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 We-Vibe Tango X is rechargeable with one of the longest-lasting batteries of any bullet vibrator I’ve tested. It lasted 105 minutes on high power during our test – especially impressive considering its excellent vibration strength. The few bullets that lasted longer, like the Dame Zee and Satisfyer Ultra Power Bullet 5, are weaker than the Tango X.

It’s a great option if you forget to charge your toys between uses or enjoy long sessions!

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 We-Vibe Tango X has excellent build quality. The silicone handle and buttons are a nice improvement on the original Tango. The silicone adds some padding, which reassures me that it’s less likely to break if I drop it. And it adds a luxurious feel and grip.

The ABS Plastic is comfortably smooth and feels sturdy – not overly lightweight or cheap. The bullet feels well-made overall.

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 We-Vibe Tango X is 100% waterproof, which makes it very easy to clean. You can submerge this bullet while scrubbing it with soap and water without fear of damage.
