The Uno is a great vaginal and kegel exerciser for women. Discreetly placed, the ball has a nice little counterweight inside which will gently and subtly remind you to squeeze those muscles. There is an area on the bottom for finger placement during insertion and the silicone removal handle is very soft, and if placed correctly, will not make you uncomfortable. The ball is about an inch and a quarter and with a bit of lube is good for beginners to more advanced users, depending on how developed your internal muscles have become. I much prefer the single ball to the double ball since I am a bit short and the dual ball system leaves me feeling a bit uncomfortable.

There is absolutely no odor with the Uno. The silicone covering is very soft and the removal cord is extremely flexible. The ball has a couple of raised waves and ridges that heightens the internal stimulation, and there are four depressions which add to the texture and increases the grippiness of the egg. The Uno is firm with a soft, non-irritating silicone wrap. Be sure you use a little water based lubricant prior to insertion! This is a great texture for all manner of users from beginning to the more advanced, and the size can be beneficial for everyone as well.

The ball is about 1 1/2" in diameter and is wrapped with soft, textured silicone. The removal cord is looped and about 3 1/2" long. I like the shape and texture of the silicone; it seems to add to the sensations and helps with the gripping. The removal cord is very strong and a bit stretchy. This is a great size for beginners and smaller women. Since there is only one ball, there isn't such a full feeling and it allows you to concentrate on the movement of the counterweight inside. This is a great exerciser to wear all day. The finger area for insertion is a wonderful addition and it really helps for placement. I was okay with the sample lube but really do prefer my water based lubricant.

This is a great single ball vaginal exerciser. The insertion area and the removal cord are well thought out and appreciated. The raised and depressed patterns in the silicone wrapping are a nice addition and add to the stimulation. I wish the internal weight was a bit greater; it seemed kind of light but overall, this is a great ball. I loved the size but wish it was more oblong for other stimuli and to allow harder gripping.

The Uno is fairly easy to clean as long as you take care with all the ridges. I use a toothbrush designated for toys and scrub all the patterns very well with soap and water. I rinse it very well and allow it to air dry since I do not like lint on my toy. I only use water based lube since it is internal and also silicone. I store this in a zip lock bag with my other toys. I would not recommend leaving it loose since silicone has issues with other silicones and components.
