This toy can be used as an internal toy for g-spot stimulation. Depending on your anatomy, it may or may not be curved to hit your g-spot. It can also be used externally on your clitoris or other erogenous zones, and it works decently except it is very broad stimulation. This toy is a little big to fit into couple's play, but to tease or for solo use it works well. It can also be used in a bath or shower since it is waterproof. This toy is perfect for beginners because it's a smallish size and made of a body safe material, but size queens should stay clear of this toy.

The Uma is 100% silicone, so it's completely body safe and easy to sanitize. It is non-porous, hypoallergenic, and latex and phthalates free. The toy internally is plastic, with the outside covered by really silky silicone, and the silicone doesn't attract as much lint as some other silicone toys. It doesn't smell or taste like anything, either.

There is no texture to this toy. It is completely smooth, so if you like texture, you might not enjoy this toy. If you like smooth toys or you’re new, you'll probably like the texture of this toy. However, there is a little bit of a drag to the silicone, so you might want to use lube when you play. Just make sure to use water-based lube, because silicone and oil-based lubes will ruin the silicone on your toy.

The Uma has a super sexy shape. It's slightly curved and smoothly rounded on both ends. The curve is supposed to hit your g-spot, but for some (myself included), it won't hit that magical spot. Its design isn't realistic, but if someone saw it they might have a guess to what it is.

Size-wise, it's a bit small. It's about 7 inches, with 4 being insertable. It's about 1 1/4 inches in diameter at the insertable end. It definitely tampers out a little before enlarging to the end where the buttons are. This size would be perfect for beginners, but advanced users or size queens might be a little disappointed.

The Uma is a pretty powerful toy, with 7 vibration levels and 7 vibration patterns. The vibrations are deep and not buzzy. Most people have said this toy is quiet, which it is on the lower settings. However, I think it can definitely be heard through walls on the more powerful settings. The vibrations can be felt near the end of the vibrator instead of the middle like some internal toys.

The control buttons are on the bottom of the wider end of the Uma. The buttons are really difficult to press and hurt your fingers a little bit. There is a +, an interesting design, and a - button. To turn on the Uma, you press and hold the + button, and continue going up by pressing the + button. The - button lowers the speed, and unfortunately, you have to go to the lowest level and the press the – button and hold it to turn it off. The middle button alters the patterns.

Here are the patterns:
1. Steady
2. Minor throbbing
3. Roller coaster
4. Throbbing with a pause
5. Quick pulses
6. Faster throbbing
7. Slow pulses

This toy is also waterproof, and although I haven't tried it, the charging port is magnetic so it is sure to work if it is not submerged for long periods of time. Oh yes, it is rechargeable. It takes sometime to initially charge it, but once the charger light is steady, it is ready. Then it lasts a pretty decent amount of time.

The Uma is very easy to care for since it is waterproof. You can wash it with soap and water or with some toy cleaner. Since it's silicone, you can also sanitize it by putting it in 10% bleach solution (Don't dish wash or boil this baby since it has motor parts that will totally get ruined by heat).

To care for your toy, only use water-based lube for use because silicone or oil-based lube will damage the silicone on your toy.

The box it comes in is perfect for storage as well, so you can keep it in there along with the charger.

The Uma came in a black box that slid out of a purple and white box with pictures of the toy on it. The black box is really simple and sturdy and holds the Uma in a place shaped out like it. It also has a small compartment lifted by a tab that includes the info packet and the charger. Overall, I really like the box and I store my Uma in there.

I tried this toy out internally with some lube and it was really easy to insert, but it seems light and I could not find my g-spot with it. I then tried it externally and it felt a little too broad. However, it is a power house, so I was able to get off using it externally, but not internally. I do like that it is rechargeable, body-safe, and easy to clean.
