The device is very convenient and easy to use with push button operation. The wireless, thin and light design wears inconspicuously under clothing, allowing you to exercise easily even on the go. Exercise while reading a book, watch TV, do housework, take a walk, stay at home, work, go on a business trip, or even take a vacation. The device has shown positive results in improving and shaping not only the buttocks but also the thighs. It can relieve muscle pain and make muscles contract and relax rhythmically just like electric massage.
