I would highly recommend this product. I own a set of Ben Wa balls that are wrapped in silicone and attached to a string, and they hold no light to this product. These are simply amazing.

Not For Everyone
These Ben Wa Balls are supposed to bring you to orgasm and help you with your kegal exercises. This was not the case for me. I inserted them and I felt absolutely nothing. They didn't give me any sexual satisfaction and I had no problems keeping them in so they weren't helping me with my Kegal exercises. These are just a big hassle to get out and not really worth it.
