Power vs Frequency Graph
How Strong Is Each Power? 

One of the main reasons the FemmeFunn Ultra Wand is a favorite of mine is that it packs excellent power while remaining easy to maneuver from its compact size. In fact, every wand vibrator I’ve tried that has more power is larger and heavier than the FemmeFunn Ultra Wand. 

Now this vibrator does have limited power range. There are only three power levels and they’re all pretty close together. This wand comes out of the gate with a bang – I rate it’s lowest power level a 6 out of 10. 

I personally don’t mind starting out at that 6/10 level – it’s strong but not overwhelming to me. But if you usually need gentle levels to warm up, you might consider a wand with a wider range like the Lovense Domi or Dame Com.

While there are wands with even more extreme power (see the Doxy Die Cast), the FemmeFunn Ultra Wand’s power will be plenty for most people. I personally don’t even need the second or third power levels. I usually stay on the first setting which is enough to bring me to orgasm on its own. 

The FemmeFunn Ultra Wand is also cheaper than any of the more powerful wands I recommend. 

The Doxy Die Cast R has an exceptional top vibration strength, but a poor power range.

It’s tied with the BMS Palmpower Extreme and Magic Wand Waterproof as my most powerful rechargeable wand, and its intensity is second only to the corded Doxy Die Cast. But all the vibrations feel strong or extreme – there are no gentle or moderate starting powers to use as a warmup. If you’re sensitive to overstimulation, you’ll probably need to use another vibrator first or consider a wand with a broader power range, like the PalmPower Extreme and even the corded Doxy Die Cast.

As someone who prefers moderate stimulation, I find the Doxy Die Cast R’s first setting decently comfortable without a prior warmup – but only if I press it very firmly against my body. Doing so slows down the motor and makes it feel less intense. And when I use the Doxy Die Cast R, I never make it past the first setting because I don’t need any more strength.

But it’s excellent for anyone who exclusively needs enormous power. The very first setting with a 7.33 out of 10 strength will meet you at the intensity you want, without having to tap through lower power levels first. And its top strength of 9 out of 10 will be more than enough for the average user. Only the corded Doxy Die Cast is stronger, but it’s hardly a noticeable amount.


Vibrations: Frequency (Rumbliness)


Rumbliness Rating 7.5 6.1
Power vs Frequency Graph
Frequency on Low Power 69 Hz 86 Hz
Median Frequency 74 Hz 105 Hz
Frequency on High Power 80 Hz 118 Hz
Power and Frequency Balance 7.3 7.1

The FemmeFunn Ultra is best for people who enjoy moderately rumbly to neutral vibrations. It has above average rumbliness, but it’s not extreme. (By the way, if you prefer buzzy vibrations, consider the FemmeFunn Booster Bullet or FemmeFunn Ultra Bullet – two of my favorite small, buzzy vibrators!)

The FemmeFunn Ultra Wand’s first two power levels feel moderately rumbly, and the highest level feels neutral. Since even the first two settings have substantial power, you’ll likely spend a lot of time with these – so you’ll experience some light rumbliness as you play. 

But this may or may not be a good fit depending on your preferences. We rate more rumbly wands higher since that’s most people’s preference. But many prefer more neutral vibrations and some prefer buzzy.

FemmeFunn Ultra Wand vs Lovense Domi vs Dame Com - Vibration Power vs Frequency Graph

If you prefer more extreme rumbliness, the Dame Com is a moderately-powered, more rumbly option. And the Lovense Domi 2 is a high-powered, more rumbly option. Each is a bit more expensive than the FemmeFunn Ultra Wand.

If you enjoy rumbly vibes closer to the center of the spectrum, then the FemmeFun Ultra Wand is an all-around great toy at a reasonable price. I personally enjoy the vibration feeling from the FemmeFunn Ultra Wand, and it’s one of my favorites.

We rate rumbly wands higher than buzzy wands since most people prefer this. However, it’s up to your personal preference.

The Doxy Die Cast R is a buzzy wand vibrator, so it’s best if you enjoy vibrations that target more at the surface. None of the settings feel rumbly. The gentlest setting has a neutral feel, and everything stronger is moderately to extremely buzzy.

While the corded Doxy Die Cast is comparably buzzy on its upper settings, its lowest two settings are rumbly. So it provides a more versatile experience than the rechargeable. If you want some rumbly settings too, I’d consider the corded Die Cast or the BMS PalmPower Extreme.

The Doxy Die Cast R’s motor slows down and can feel softer and more rumbly when pressed very firmly

One unique aspect I’ve found is that the Doxy Die Cast R’s motor slows down quite a bit if I press the head firmly against my body. By slowing the vibrations down, they approach a more rumbly feeling. I personally enjoy how I can alter the intensity and rumbliness by varying the pressure I apply. If you don’t necessarily need rumbly settings but still enjoy them, you may like experimenting with the Die Cast R’s pressure to find something that feels great to you.

Others will prefer something steadier regardless of the pressure applied. While the corded Doxy Die Cast’s motor is also slightly affected by how hard you press, it’s a much less noticeable effect than with the rechargeable version.

I gave the FemmeFunn Ultra Wand one of the highest ratings for comfort and ease of use!

The compact size is easy to hold and maneuver. The head isn’t squishy, but the neck is extremely flexible so it’s still comfy. I’ve found when some wands are flexible, you lose the ability to apply pressure – but this is not the case with the Ultra Wand. It’s the perfect size to comfortably leverage the handle and push the vibrations deeper into me.

The head is also an excellent size for versatile stimulation. For such a short wand, the head is fairly tall – but not too wide. So I can press the top of the wand to my body for more focused stimulation, or use the tall side of the head for more broad stimulation.

The top of the FemmeFunn Ultra head can be used for focused stimulation, while the side is useful for broad stimulation

It has two buttons used to control it. One lets you cycle through a series of 3 power levels and then several patterns. The second button is a “power boost” button. This lets you turn any one of the power levels or patterns up to full power with one click. 

While I do wish there was another button to step back down in power (instead of cycling through the settings with one button), the power boost button is a nice touch. 

FemmeFunn Ultra Wand Buttons
The bottom button cycles through three intensities and multiple patterns. The top button provides a burst of higher power when pressed.

The silicone handle is also exceptionally comfortable to hold. Overall, this is one of the wands I reach for most often. Which is one of the strongest testaments I can give it!

The Doxy Die Cast R is comfortable and easy to use for a heavy, full-sized wand.

This wand’s substantial weight both positively and negatively affects the wand’s comfort. Anytime you use it with the wand’s head pointed down (like on your back), the heavy weight adds excellent natural downward pressure. So you don’t have to leverage the wand with your arm or wrist much. But this also makes it slower to maneuver and can be tiring when you’re holding the wand up – which happens more frequently during sex than solo use.

The large, round head provides a really broad, comfortable surface area in contact with your body. Though it’s trickier to limit contact to a precise area than with a smaller head. The head’s silicone is slightly plush, which feels comfy and luxurious. And the neck has a bit of flexibility, which keeps it comfortable when applying firm pressure.

The handle is a comfortable size to wrap my hand around, and its cast aluminum construction does an excellent job of preventing much vibration in the handle itself – keeping them focused at the head. I typically hold the wand close to the head because the weight distribution is best there. With that grip, my fingers aren’t near the buttons, so I don’t accidentally press them. Though I need to adjust my grip to change the setting, but I don’t find it distracting.

The controls are simple to use and get you to your preferred setting quickly, with separate buttons to increase or decrease the power. You can turn on the pulsing setting by pressing and holding the power button. The two “+” and “-” buttons also allow you to adjust the speed (not intensity) of the pulses.


Use During Sex


Use During Sex Rating 9.3 7.6
FemmeFunn Ultra Wand Fit in Tight Space
Doxy Die Cast R Fit in Tight Space
Spooning 10.0 7.5
Doggystyle 9.5 9.0
Modified Missionary 9.0 7.0
Cowgirl 8.5 7.0

This wand is also one of my favorites to use during sex. It performs best in Spooning, Doggystyle, and Modified Missionary positions. 

The extreme flexibility of the neck makes it trickier to apply leverage in the Cowgirl position. But that’s only if you’re looking for very firm pressure. 

And the flexible neck is a big part of the reason I really enjoy this wand in other positions. Its extra bendiness and slim head make it easy to maneuver and fit into tight places. 

The handle is the perfect size to give you a good grip with nice leverage. But it’s short enough that it doesn’t take up too much space during sex. Overall, this is a great option to use with a partner!

The Doxy Die Cast R is good to use during sex.

It’s best in positions where you’re not facing your partner because there’s plenty of space in front of you to maneuver the handle without it bumping into your partner. So you can easily position the Die Cast R wherever you need it.

The broad head keeps the wand in consistent contact with your clit and distributes the pressure evenly so the vibrations travel well. In Spooning and Doggystyle positions, the handle is long enough to rest against the bed to help prop the wand at a good angle. So your arm doesn’t get tired despite the substantial weight.

When you’re facing your partner, you have to get a little more creative with your body’s positioning – possibly leaning back to open up more area for the large head to fit closer to your clit. Thankfully, the vibrations are powerful enough that they are impactful, even if the head is nearby instead directly in contact with your clit. Because the head is so large, it can get pressed into your body with a lot of heavy movement, which can be a bit uncomfortable at times but is not a major issue.

But if face-to-face positions are a priority, a wand with a smaller or angled head, like the BMS PalmPower Extreme, is better.


Noise

Decibels on Low Power 44.0 dB 48 dB

Low Power Inaudible Audible
Middle Power Audible Audible
High Power Audible Audible
High Power with Box Fan Inaudible Audible
High Power with Music Inaudible Inaudible

This is not one of the quietest wands available, but there are some solutions to help. 

We test each wand to see whether someone can hear it standing directly on the other side of a closed bedroom door. When I use the FemmeFunn Ultra Wand in our bedroom and my partner listens at the door, I can use the lowest power without him hearing. But he can hear the top two settings.

But, when we turn a box fan or some music on in the bedroom, it becomes inaudible on all power levels. 

If sound is especially important to you, the Viben Sultry has comparable power to the FemmeFunn Ultra Wand, but remains inaudible on all power levels without needing a fan or music. And of course, less powerful wands are also quieter.

But for the FemmeFunn’s power, its noise is reasonable.

The Doxy Die Cast R is quite loud.

When we tested whether my partner could hear it from behind our closed bedroom door, he heard every setting. Even after I turned on a box fan in the bedroom my partner still heard the Doxy Die Cast R’s top setting – although he noted that then he could only hear it when I moved the wand around, and he said he’d definitely have to actively listen for the sound to notice it.

Playing music in the bedroom successfully prevented him from hearing the wand on any setting.
If you have housemates and/or discretion is important, the Magic Wand Plus is a comparably powerful wand that was inaudible at least on the lowest power setting. And both a fan and music mask the noise.

The FemmeFunn Ultra Wand has decent compatibility with attachments.

It doesn’t work with attachments designed for full-sized wands like the Magic Wand Rechargeable. But a few brands make attachments compatible with mid-sized wands like the FemmeFunn.

Le Wand has several attachments designed for the Le Wand Petite, and all of these fit the FemmeFunn Ultra Wand too. These provide various kinds of stimulation like G-spot, anal, prostate, and dual-stimulation. They also have textured caps to change how the wand’s clit stimulation feels.

Both attachments designed for the Lovense Domi also fit the FemmeFunn Ultra Wand. These provide similar stimulation to those mentioned above, and the male attachment also provides penis stimulation.

The Doxy Die Cast R has fantastic compatibility with wand attachments.

Most attachments are made for full-sized heads like this one. In my collection, I found many that fit, providing a wide variety of stimulation types. You should have no trouble finding plenty of options.

For a compact wand without a curved handle, I was surprised at how well the FemmeFunn Ultra Wand works with mounts. 

I test all my wands with Liberator’s mounts for hands-free play: the Axis and Wanda

Wand In Use with Axis Overlay
My typical position when using the Liberator Axis mount (demonstrated with BMS PalmPower Extreme)

The Axis enables you to lie face down over the mount while it holds the wand between your legs. I typically use this mount for hands-free stimulation during sex from behind. The FemmeFunn Ultra wand works fairly well with the Axis, but you need to be aware of your body’s position to keep the wand in contact with your clit. 

It’s not as effortless to get good clitoral contact and pressure as a wand with a curved handle or angled head. My favorites to use with the Axis are the Dame Com and BMS PalmPower Extreme.

When it comes to the Wanda mount, the FemmeFunn is awesome! While straddling the Wanda, it’s very easy to lean forward or backward and adjust the pressure and stimulation you get from the FemmeFunn Ultra Wand. Or you can bend all the way forward over the mount, and there’s plenty of room for penetration from a partner. 

We test our wands for hands-free stimulation using the Liberator Axis and Wanda mounts.

The Doxy Die Cast R works wonderfully with both mounts.

In the Liberator Axis, the large, round head provides plenty of surface area to press against comfortably. At 2.5 inches, its head is wider than most, which helps it reach your clit more easily than most straight wands. The strong vibrations travel well to provide great stimulation hands-free. The handle stays securely wedged in the mount.

In the Liberator Wanda, you can kneel above the mount for hands-free stimulation solo or with penetration from behind. The head sticks up quite a bit past the fabric, so you can’t sit directly on the mount as you can with some short wand vibrators. But it provides excellent stimulation when kneeling over it. The broad, tall head is great at distributing pressure evenly so you can comfortably lean against it.


Battery Life

The FemmeFunn wand lasts around 75 minutes continuously running on its highest power.

This is toward the lower end of our wand vibrators’ battery lives.

If you want a wand with this level of power that provides longer playtime between charges, consider the Magic Wand Rechargeable.

But keep in mind, if you won’t be using the highest strength the entire time, the FemmeFunn Ultra Wand will last longer.

The Doxy Die Cast R is rechargeable and has a decent battery life, lasting for 75 minutes on its highest power in our test. Considering this wand’s enormous strength, that’s a reasonable battery life.

There is an automatic shutoff after 20 minutes of continuous use, but you can turn it back on immediately. You cannot use the Doxy Die Cast R while it’s charging (very few wands allow that – the Magic Wand Rechargeable is one that does).


Build Quality


Build Quality Rating 8.5 8.5

This wand is covered entirely in silicone, including the buttons, which feels very luxurious and comfortable. Even though the neck is more flexible than most wands, it still feels thick enough, so I’m never worried it will break from firm pressure.

The Doxy Die Cast R has great build quality.

The cast aluminum handle feels very sturdy, and the slightly flexible neck feels strong, so I’m not afraid to apply pressure. The silicone head is slightly plush, which feels comfortable and high-quality. It feels well-made and luxurious.

The motor does have a slight waver at times, where it will dip or raise by 1 or 2 Hz. I can hear the waver (listen below), but it doesn’t impact my experience – I can’t feel this slight difference.

The slight waver in the motor, which you can hear, but it’s not really felt in the vibrations during use

I want to note that when we purchased the Doxy Die Cast R, the first one we received arrived with a defect. It would shut off randomly despite having a full charge, and the power would dip substantially. These issues were noticeable immediately upon using the toy (not something that developed over time). We believe something likely happened during shipping.

We contacted Doxy support right away, and they replaced it quickly. We had to send a video showing and explaining our issue and then cut the charging cable. They sent a new product within 3 business days of our initial email. And our new product has worked great.

Our rating for build quality is based on the undamaged wand we received. Doxy also has a 2-year warranty when you register your wand for free on their site.
