Touted as one of the most powerful vibes available, I can attest to the fact that this vibrator is incredibly powerful. Even the lowest setting has a powerful thud-thud-thud, the higher settings are increasingly powerful and the transition between each setting is smooth (provided you can work the buttons, but more on that later). Speaking of smooth, the Uma is incredibly soft and made of silicone. This means that it is velvety, but also means that silicone lubes are not compatible with this vibe and that is a shame since silicone is my go-to lube and the velvety texture (which, again, I adore) kind of necessitates the use of some type of lube.

In regards to scent, there is a faint plastic smell, but it isn't anything that is a turn-off. In fact, in order to detect the plastic scent, I have to literally place the Uma under my nose.

Despite the powerful vibrations, this vibrator is still surprisingly fairly quiet. While you can hear it under the covers - it certainly won't wake the kids and I doubt that it's use will be detected by other adults with my bedroom door closed. The Uma doesn't use batteries (yippee!!), it has a charger that charges the unit in two hours. The product manual states that two hours of charge time yields two hours of play. I haven't verified that claim, but according to my experience, that seems about right. Another thing I like about the charging functionality is that a red light blinks when the unit is charging -- when it's done charging, the light stops blinking and stays red, so there's no guessing or trying to recall what time you plugged it in. Yet another benefit of the Uma is the ease of cleaning: warm water and soap and a quick dry with a towel, and you're all done -- no funky grooves or crevices with which to be concerned.

In regards to size, the Uma is what I would consider to be in the medium range. It's bigger than a bullet, but certainly not unusually large. It's overall length is about 7 inches, insertable length is about 4 inches. The diameter is 1.25 inches. It has a gentle curve designed to hit the G-spot. Personally, I find this to be a fabulous clitoral stimulator and find myself returning to that area again and again.

My biggest complaint with this vibrator is the location of the buttons: the are at the very end and it takes a little more pressure to change the vibe setting than I would prefer. I think, however, that there may be a learning curve with this, so I'll have to update this review in a couple of months.

Powerful vibrations, smooth silicone, and rechargeable - what's not to love? This has become my favorite and seems to be the go-to that delivers strong orgasms quickly. The Uma has never let me down!
