The Smart Knee Massager uses a combination of heat therapy, vibration massage, and air compression to provide targeted relief. The heat helps improve blood circulation, reducing stiffness and promoting relaxation. The vibration massage soothes sore muscles and joints, while the air compression gently applies pressure, improving mobility and reducing discomfort. Simply wrap it around your knee, select your desired settings, and enjoy a soothing, hands-free therapy session in minutes!
