I was rather excited to try this out. I was a bit leery of some other smart balls, or ben-wa balls, but this product made the beginner user a lot more at ease with insertion and retrieval. The Teneo Uno is a lot less scary for first time users and, with the soft silicone design, it gives you ease with use and cleaning. The sensation is great, it would be nice if it was a little stronger but was great none the less.
