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 Viben Obsession is significantly stronger than any of my non-wand vibrators, even on its softest setting. 

There are three power levels. The lowest starts at 7.7 out of 10 vibration strength, and it goes up to 8.5 on high. It doesn’t provide any warm-up, which is a bummer because I typically need softer power when I’m starting out. Otherwise, the vibrations feel too overwhelming.

I can only use the Viben Obsession’s lowest power level without feeling irritated. And even then, I need to use it over my clothes.

I find the second and third levels wildly unpleasant. They’re extremely buzzy which feels overwhelming and uncomfortable combined with the immense strength. I’ll talk more about that in the next section.

Many wands have a broader power range than the Viben Obsession – packing extreme power on high, but beginning gentler on low. I prefer these wands like the Lovense Domi, BMS PalmPower Extreme, among others.

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.

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 wands with rumbly vibrations more highly than those with buzzy vibrations. Most people prefer rumbliness. But, there is definitely variation in peoples’ preferences. 

For example – I really enjoy neutral or moderately buzzy vibrations when they’re moderately powerful (roughly vibration strengths between 4 and 7). But when vibrations are both extremely buzzy and immensely powerful they become unbearable to me.

And that’s the problem with the Viben Obsession – it’s extreme in both power and buzziness. 

It’s one of the few wand vibrators we’ve tested that is already buzzy on its lowest setting! And on high, it’s the buzziest of all our wands. On the second or third power, I don’t even like to touch it to any part of my body. And I definitely don’t want it near my clit!

You can find comparably priced, powerful wands with better rumbliness. Whether that’s extreme rumbliness, like with the Lovense Domi, moderately rumbly like the Viben Sultry, or more neutral  like the BMS PalmPower Extreme. I enjoy each of these wands, and each provides powerful stimulation with deeper, more enjoyable rumbliness.

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.

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. 

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 Viben Obsession has a comfortable handle that’s relatively narrow for a full-sized wand. People with small hands like me will find its slim, silicone handle comfortable and easy to grip. I also don’t feel any uncomfortable vibrations in my hands as I do with some wands. This surprised me since the Obsession is extremely powerful.

The head is large, which means you can’t fit it into tight areas, but it provides wider stimulation instead. Since the vibrations are so strong, you probably won’t need to position its head in a precise spot – it broadly stimulates the entire area. It’s also lighter than other full-sized wands so maneuvering it is fairly easy.

The head is firm, but the neck is extremely flexible which keeps it comfortable.

The controls are great. They’re easy to feel without looking, but I don’t accidentally press them. And you can both increase or decrease the power, which is necessary since this wand is so strong. You may need to step back down sometimes.

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!

In this section, I try to rate how easy it is to use the wand during sex. I consider aspects like whether a wand limits how my partner and I can position our bodies and whether maneuvering the wand and keeping it in contact with my clit during sex is easy. 

I try to compartmentalize how the vibrations themselves feel. But I experience such discomfort from the Viben Obsession’s extremely buzzy vibrations during sex, it’s impossible to separate that component out completely.

With all the movement happening during sex, the Viben Obsession’s wide head bumps into my legs and other areas that I don’t want to be stimulated. And since the vibrations are so powerful and buzzy it feels uncomfortable and distracting.

This is especially the case in positions like Missionary or Spooning where I can’t lean back to create more space for the wand’s head. The Viben Obsession’s firm head also bumps uncomfortably into my pubic bone in Cowgirl.

The Obsession’s vibrations seem to feel more diffuse in Doggystyle, and I’m able to enjoy the lowest power level a bit. And the Viben Obsession has a long enough handle that I can support its weight by resting the wand’s base on the bed. So my arms don’t get tired using it in this position.

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 Viben Obsession is my loudest wand vibrator. I find its noise distracting, and it’s certainly not discreet. 

My partner can hear it from the other side of our closed bedroom door on all power levels. And it’s the only wand that was not drowned out by playing music in the bedroom. My partner could still hear it on the other side of the door! 
The Viben Sultry and Magic Wand Rechargeable are comparably powerful, but much quieter (and more rumbly too!)

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 Viben Obsession has excellent compatibility with wand attachments. As a full-sized wand, the majority of attachments are designed for heads this size.

There are compatible attachments for a range of stimulation including G-spot, prostate, anal, penis, clitoral, and dual-stimulation. Below are the wand attachments we’ve tested for compatibility with the Viben Obsession.

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. 

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. 

I test my wands with the Liberator Wanda and Axis mounts which hold your wand so you can play hands-free. The Viben Obsession fits well with both mounts. 

The Axis works best lying on your stomach while the mount holds the wand between your legs. The Viben Obsession’s head rests in a good position for clit stimulation, sticking out just past the fabric. 

In the Axis, I prefer wands with an upward curve or angle like with the BMS PalmPower Extreme which put a little more pressure on my clit. But since the Viben Obsession’s power and buzziness are so intense, I’m happy to have slightly less contact with my clit.

The Wanda mount also holds the Obsession in a good position. I can comfortably straddle the mount while keeping the head in contact with my clit. The broad head provides plenty of surface area to lean against. And the flexible neck is comfortable when I press my weight back on it.

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 Viben Obsession lasts around 65 minutes on high power, which is shorter than other comparably strong wands. You’ll have to be vigilant about charging between uses.

If you tend to forget to charge your wand like me, you might want something with a longer battery life, like the Magic Wand Rechargeable. 

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 Viben Obsession’s construction is decent overall. The buttons feel a little clicky. And the neck feels somewhat flimsy and makes a weird noise when I apply pressure. This makes me more cautious to press the Obsession as firmly as other wands. 

Other than that, the silicone and construction quality feels good.
