G Balls 2 - Assorted Colors

G Balls² are the first Kegel sensor balls in the world controlled by a mobile App. Using bio-feedback technology, the stronger the user squeezes, the stronger the vibration G Balls² provides. Designed for both iOS and Android, the Magic Kegel App can then be used as a personal smart coach by guiding the wearer through six different training programs with four levels of difficulty. Kegel training will never be the same!
