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 Satisfyer Ultra Bullet 5 is the best budget-friendly option if you only need low to medium power. There are 5 total power levels, with the first starting at 1.25 out of 10 vibration strength. The highest setting reaches 5.25 out of 10, which is not intense, but I can orgasm with it.

These settings give you plenty of gradual power levels in that softer range. So it’s an excellent option for those who are easily overstimulated. However, it won’t be enough for those who crave strong vibrations.

For intensity lovers, I’d recommend the Blush Limited Addiction instead. This budget-friendly bullet starts at 5 and reaches a 10 out of 10 vibration strength. Since it begins with fair power, it’s best for those who don’t need very gentle settings.

If you want a bullet covering the spectrum from gentle to intense, you’ll need to increase your budget a bit. The Pillow Talk Racy is the most budget-friendly option that has plenty of levels covering both mild and strong stimulation.

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.

Rumbly vibrations are what people most often prefer, so we rate those higher than buzzy ones. Though many people prefer buzziness, so consider what you enjoy.

The Satisfyer Ultra Power Bullet 5 is moderately buzzy. While the two softest power levels are rumbly, the top 3 levels I use most are buzzy. As someone who enjoys the neutral-feeling range, I’m bummed that this bullet skips right over it.

But this is to be expected with the cost – most cheap bullet vibrators are buzzy. If you want rumbly vibrations, you’ll need to increase your budget. The most affordable option that falls completely in the rumbly section is the We-Vibe Tango if you can find it, otherwise go for the Pillow Talk Racy, which is also very rumbly. The We-Vibe Tango X is the most rumbly but a bit pricier.

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.

You can get reasonably precise stimulation using the Satisfyer Ultra Power Bullet 5’s tip or more mid-focused stimulation by pressing its side to your body. The tip is great for direct stimulation in a fairly small area. And I also love the indirect stimulation of pressing the side to my lips. If you prefer broader stimulation, some other mini vibrators like the Dame Pom or We-Vibe Touch X may suit you better.

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 Satisfyer Bullet 5 is easy to hold and leverage. The shape is bulbous – bulging out in the toy’s middle and gradually narrowing toward the tip. It feels a little awkward in my hand but doesn’t inhibit good pressure or a firm grip.

The vibrations don’t travel into my hand either, so griping for long periods is comfortable.

There’s one button to control the vibration intensities and patterns, so unfortunately, you have to cycle through them all to get to the one you want. I prefer the bullets that let you power up or back down, like the Blush Limited Addiction. If greater control is a priority to you, the Satisfyer Ultra Bullet 8 is about the same cost, and you have greater control over it with the Satisfyer app.

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 Satisfyer Ultra Bullet 5 is alright during sex. The bulbous shape and short length make maneuvering more awkward during sex than by yourself, but it’s not impossible. The tapered shape makes it challenging to keep clitoral contact in positions facing your partner like Missionary.

In positions facing the same direction as your partner (like Spooning), it’s easy to keep this bullet pressed to my clit. Though leveraging it for good pressure is a little tiring on my fingers since it’s so small.

I prefer longer bullets during sex like the Blush Limited Addiction or Pillow Talk Racy. These allow you to loosely grab the end and adjust the angle and pressure with a light twist of your fingers.

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 Satisfyer Power Bullet 5 is inaudible on all power levels from behind a closed door. So it’s a safe option even if you have housemates. Part of why it’s so quiet is that it’s a mid-strength bullet.
There are also plenty of bullets out there that get stronger but still cannot be heard from outside your bedroom. The Lovense Ambi, Pillow Talk Racy, and Blush Limited Addiction are a few of my favorite discreet bullet vibrators.

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 Satisfyer Bullet 5 has great battery life, lasting nearly two hours on high power. So you can enjoy multiple sessions with it between charges.

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 Satisfyer Ultra Power Bullet 5 has reasonable build quality for its affordable price. The lightweight plastic definitely feels a little cheap. The button on the end takes some effort to press, which can be frustrating. But I’ve had no issues with performance or the toy breaking.

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 Satisfyer Ultra Power Bullet 5 is very easy to clean. It’s IPX7 waterproof which is completely submersible. So you can clean it with soap and water without worry – and even take it into the bath with you!
