Developed by some very innovative technology, the SMARTBALLS DUO is extremely quiet and smooth running with steady, fast rotation of the inner balls. An ergonomically shaped finger hollow makes insertion easy. So a woman can go about her day without interruption and at the same time be training diligently.
The SMARTBALLS can be inserted in the vagina lengthwise and with a drop of waterbased lube, the retrieval band remains outside the body.
Some may be a little disappointed that using vaginal balls doesn't lead to orgasm. However, sex after training is even more passionate and enjoyable. A woman has more sensation during sex. And for the man, the snug hold feels great. So start your training today!
