[0002] The massager is a new generation of health care equipment developed based on physics, bionics, bioelectricity, traditional Chinese medicine and many years of clinical practice. It not only has eight simulation functions, allowing you to truly experience the wonderful feeling of eight functions of acupuncture, massage, hammering, cupping, scraping, weight loss, and immune regulation, but also has the unique effect of treating hypertension. Using several independent soft-touch massage heads, it can relax muscles, soothe nerves, promote blood circulation, strengthen cell metabolism, enhance skin elasticity, relieve fatigue, significantly reduce various chronic pains, acute pains and muscle soreness, relax the body to reduce stress, and reduce skin wrinkles.
