All Hail Powerful Uma

This velvety-soft rechargeable silicone vibe delivers strong vibrations and pulsations with a high-quality motor. The only drawback is that one button is tough to use, as you have to push hard in the right spot.
silicone, rechargeable, versatile, sexy-looking, very powerful
The button that switches pulsation patterns is tough to use

useful review


This rechargeable vibe is unusually strong, features different levels of intensity as well as seven very interesting pulsation patterns that can themselves also be adjusted for intensity--a rare feature.

Material / Texture

It's made of velvety smooth silicone, and it's miraculously very low on the lint-attracting index. The toy is seamless, except for around the two metal battery contacts that are also buttons that turn it on and raise and lower intensity. The ring around these appears to be very tight, however, and designed not to let water through.

Design / Shape / Size

I love the curve of this dildo, which makes it work great when it's inserted for solo play while you are in a seated position: rocking it back and forth in this position will drive you wild. The bulb at the end helps Gspot stimulation and also makes it feel filling while the narrow neck makes it feel comfortable. It's a size and shape that most people would enjoy for this readon.

I also used it externally, and I found the curve to also be amenable to this use.

Functions / Performance / Controls

This vibe has three closely-spaced buttons on the end that gets charged: one + silver button that you hold to turn on and click repeatedly to cycle through increasing intensities, one - slver button that you hold for a few seconds to turn off and that you click repeatedly to incrementally lower the intensity of the vibes, and a plastic button in the middle that is especially hard to decompress and cycles through 7 different pulsation patterns. One impressive feature, which I don't think I've seen in any of the many vibes I've tested, is that you can adjust the intensity of each pulsation pattern with the + and - silver buttons as well as adjust the intensity of the vibes when it's in steady mode.

On the one hand, I appreciate that the buttons are not easy to accidentally use. On the other hand, they require a fair amount of pressure to work, especially the one in the middle that cycles through the different pulsation patterns. The two silver buttons also serve as the magnetic contact points for the snap-on charger connection, and slightly jut out of the vibe. You can feel them slightly clicking when you decompress them. The middle button, however, is completely flush with the surface, but you have to decompress the very small center til it dips just slightly below the surface. As a result, I found myself having to make 2-3 tries before getting it to register my button pushing.

It's not very noisy at all, especially given its huge power, which approaches the Hitachi Magin Wand, but in a smaller, more concentrated package.

It's water proof, but I would be cautious about immersing any motorized toy for long periods if I wanted it to last for many years.

Care and Maintenance

It is odorless and sterilizeable with a 10% bleach solution rub down and a rinse with lots of soap and water. It's water safe, but since it has a motor, it cannot be boiled clean, and I would avoid submersing it for long periods of time in the tub to extend its life.

Never use silicone lube with a silicone product; however, there are tons of water-based lubes that will do the trick and are safe for use with silicone.
    • Easy to clean
    • Easy to store


It comes in a nice black box with a top that slips on and off and a compartment at the bottom for storing the charger. It will keep the toy safe and protected, but the box takes up much more room than if the toy came with a drawstring bag and attached pouch for the charger.

There's also a brochure with very basic instructions.
    • Good for storage
