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 Fun Factory Laya III has a fantastic, wide power range, beginning softly and finishing intensely.

The first of 7 settings is a 1 out of 10 vibration strength, so those worried about overstimulation have gentle levels to enjoy. The first couple of settings feel especially “tappy,” which is a stimulating warmup without feeling overwhelming at all.

Power lovers will also be happy with the substantial top strength of 7.75. While there are a few more powerful bullet and mini vibrators, like the BMS Swan Maximum, the Laya has plenty of strength for me and most people. I orgasm on any preset power level between 4 and 7 – I usually don’t need to use the top strength.

Steps between settings are also comfortably gradual. You can also press and hold the “+” and “-” buttons to make micro-adjustments to the strength. This means it’s easy to find your ideal intensity and keep the journey comfortable.

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 Fun Factory Laya III’s vibrations have excellent rumbliness and a rich, layered feel. The first several settings feel very rumbly, and the top two settings are neutral.

But there’s more to the Laya’s story than most mini vibrators – the Laya’s vibrations also have a unique “layering effect,” which feels like typical vibrations plus a distinct “tapping” sensation underneath them. Listen to it in the video below.

To acheive this tapping effect, the motor runs at your chosen speed (the frequencies shown in our graph above), just like any other vibrator. But the Laya’s internal software briefly cuts power to the motor for mere milliseconds causing the motor to momentarily decelerate. Then it resumes power so the motor quickly accelerates back to its main operating frequency.

This brief slowdown-speedup cycle happens within milliseconds and sounds like a thump-thump-thump tapping. And it feels like deeper, more rumbly vibrations than the main frequency (because it’s actually decelerating briefly through lower frequencies).

All this is happening so fast, many times each second, that it feels like you’re always experiencing both the main vibration frequency and a more rumbly vibration frequency at the same time.

I love this innovation because I think both rumbly and neutral vibrations have benefits. Rumbly vibrations travel deeper and stimulate more nerves beneath the surface. But neutral (and buzzy) vibrations provide a surface-level kick that I also enjoy.

On the Fun Factory Laya III’s top settings I get the benefit of both types of vibrations – the concentrated, surface-level kick from the neutral vibes and the deeper stimulation from the rumbly tapping effect. It’s not an out-of-this-world difference, but I think it improves upon ordinary vibrations. And I enjoy this feeling more than normal rumbly vibes.

I’ve noticed a similar tapping effect in a few other rumbly mini-vibrators, like the We-Vibe Touch X and Je Joue Amour, but only on their lowest levels (which are already rumbly). But the Laya III keeps this deep, tapping sensation through all its power levels, even up to the top strength. So it’s the only one I’ve tried that feels like it combines neutral and rumbly vibes.

If you prefer only rumbly vibrations, you could stick to the lower power levels of the Laya III, which have a rumbly main frequency and a deeper tapping. Or go with the purely rumbly We-Vibe Tango X.

But the Fun Factory Laya III is right in my sweet spot. My favorite vibrations have a neutral feel, with a little overlap into the moderate levels of rumbly and buzzy. The Laya III fits really well with this preference.

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 Fun Factory Laya III provides lovely broad stimulation when using its entire length to hug your vulva. Or you can get a medium amount of precision when holding it like an ordinary vibrator, pressing the tip to your clit.

So this lay-on vibrator is best for people who prefer moderate to broad precision.

I wanted to clarify this because the Fun Factory Laya is marketed as also offering “pinpoint” stimulation using the ridges. But while the ridges provide an enjoyable texture, they are too small and un-pronounced to provide focused stimulation, like a typical bullet vibrator does. Your body cannot feel each ridge on its own.

If you prefer something that offers both broad and focused stimulation, consider the We-Vibe Touch X—you can use the flatter surface for broad stimulation or the slim tapered tip for focused stimulation.

But for those who enjoy broad coverage, the Laya is excellent! It blankets the whole vulva for direct but comfortably diffuse 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 Fun Factory Laya III is very comfortable and easy to use.

Even though there’s not an obvious handle, there are several convenient and comfortable ways to hold the Laya III. It takes a little getting used to if you’re accustomed to bullet vibrators because it’s girthier and curved, but I’ve found this makes it more versatile. You can leverage it easily with your fingers or simply rest your palm over it and lightly press it to your vulva.

When lying on top of the Laya, it’s very comfortable if you’re only pressing your body lightly against it. It curves along your body and spreads the vibrations over the whole area, which keeps the direct contact comfortable.

If you want to press your hips into it, you may have to take your time to find a comfortable angle to lay the vibrator –  the Laya’s very firm, so in some positions, it can be uncomfortable to press too hard into it. If I want to press harder into the Laya, I’ve found using blankets or a pillow beneath the Laya to adjust its angle makes it more comfortable and provides some cushioning. Or you can slip your hand under your body to hold the Laya tilted at the angle you like.

When using the Laya as an ordinary handheld vibrator, you can feel the vibrations in your hand—but that’s mostly when you’re holding it in the air. I don’t feel them much once I press the Fun Factory Laya to my body, and I don’t find them distracting at all, even on high power.

The curved shape makes it easy to apply excellent pressure whether you’re gripping it or using it hands-free by pressing your hips down into it. Because it’s very firm (not plush like the We-Vibe Touch X or Magic Wand Micro), you may have to limit how much pressure you apply to keep it comfortable against your body. But with the powerful, layered vibrations, I don’t have to press hard to get excellent clit stimulation.

The buttons are positioned above the part of the Laya in contact with your clit, so pressing a button also pushes the Laya against you more firmly. If you don’t like that firm contact, you can simply move the toy away from your body briefly while you change the power.

The controls themselves are excellent. The “+” and “-” buttons allow you to tap back and forth through the 7 power levels and 3 patterns. You don’t need to cycle through power levels to return to a previous setting, as many mini vibrators require you to do. You can also press and hold the Laya’s buttons to make even more gradual adjustments.

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 Fun Factory Laya III is one of my favorite mini vibrators to use during sex.

First, you can use it as a lay-on vibrator during sex for hands-free clit stimulation (discussed in depth below). If you don’t want to hold the Laya, you can lie face down with the vibrator sandwiched between your vulva and the bed (or a pillow) while your partner penetrates from behind. This is one of the main reasons I love the Laya III and use it so much!

If you don’t want to limit yourself to the position I mentioned above, it’s also great when you hold the Fun Factory Laya and use it like a normal handheld vibrator.

In sex positions with a lot of space to maneuver, like Spooning, there are many comfortable ways to use the Laya. You can rest your palm over the toy to press its contoured shape comfortably along your body. Or you can hold the end and angle it against you for firmer pressure. It’s very comfortable and keeps great contact with my clit, even during a lot of movement.

It’s also excellent in Missionary or other positions facing your partner. The curved design helps it fit seamlessly between your bodies, even when space is limited in these face-to-face positions. The curved shape also makes leveraging the Laya to apply pressure during sex easy. Occasionally, if my partner’s thrusting fast or his body bumps into my hand, the Laya can press mildly uncomfortably into my clit since it’s so firm. But this is rare and I haven’t found it to be a major issue.

The layered, rumbly vibrations also travel deep into my body which is very stimulating during sex.

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 Fun Factory Laya III’s noise levels are sub-par. The vibrations are often very quiet, only reaching 42.1 dB on high power. But when you hold the Laya in certain ways, it makes a louder rattling sound.

The rattling mostly happens when I’m holding the toy in the open air instead of pressed against my body. So when you move the Laya off your body to adjust its position, it’s likely to make this louder noise.

When we tested whether my partner could hear the Laya behind our closed bedroom door, he began hearing the rattling sound when I turned the Laya to power level 4 and above. But when I kept the Laya pressed to my body to prevent the rattling, he could not hear the vibrations on any power level or setting.

When I turned on a low-power box fan in the bedroom to mask the Laya’s noise, my partner said he could still barely hear the Laya rattling on its top setting – but only since he was standing right at the door trying to listen for it. He didn’t think anyone would notice it in a normal circumstance.

Playing music in the bedroom successfully masked the sound of the rattle.
Since I love everything else about this toy and we live alone, the noise issue doesn’t bother me, so I still use the Laya often. But if you have housemates, the We-Vibe Touch X is much quieter.

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 Fun Factory Laya III is rechargeable and has a great battery life, lasting 103 minutes on its highest power in our test. This is longer than most of my bullet and mini vibrators, even than stronger ones. So it’s an excellent choice if you want a mini-vibrator with a long battery life.

You charge it with the included magnetic USB charging cable. One downside is that it takes 6-7 hours to fully charge, whereas most take just 1-2 hours. So you’ll want to plan ahead to keep the Laya charged. I typically charge it after every use, just in case.

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 Fun Factory Laya III has a fantastic build quality (except for the rattling sound discussed above). The body-safe silicone feels very luxurious, and the ridges provide a grippy texture I really like. It has a nice weight, which feels high-quality in the hand. I also like the feel of the button click. The buttons are raised, so you can feel them without looking. The Laya feels solid and not easily breakable, with no bendy parts at risk of overstress.

I also love the color I got—“Sage Green,” a muted, more neutral-feeling color that is rare in the hot pink world of sex toys.

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.

Since the Fun Factory Laya III is IPX7 waterproof, it’s very easy to clean. You can fully submerge it while scrubbing with soap and water without worrying about damaging the toy. And you can also take it with you in the bath!
