SMARTBALL UNO is the easy-to-use kegel training device for a strengthened pelvic floor that's especially beneficial for beginners, as well as for women with uterine conditions. Inserted like a tampon, the SMARTBALL UNO can hardly be felt when worn. Through the constant yet quiet rotation of the inner balls, with everyday movements, muscle contractions are induced, which strengthen the pelvic floor. Short, regular training sessions lead to the best results and improvements.
