With its professional massage technique, heating function, portable and cordless design, three massage speeds (high, medium, slow), and large massage area (neck, shoulders, back, waist, and calves), this massage device is highly versatile. With this oPillow massager, you can enjoy a comfortable and relaxing massage whether you are at the office or on the sofa at home. Unlike the common round massage heads on the market, the flat head massage is closer to the body part. The four nodes move simultaneously, ensuring there is no pain during the massage, just like a palm massage from a masseur. The rotation direction automatically changes every 60 seconds to ensure your body remains completely relaxed. A 15-minute automatic shut-off function prevents excessive massages. The integrated advanced heating function transfers warmth to the muscles, accelerates muscle recovery, and alleviates tension, stress, and fatigue. The intelligent control system automatically adjusts the heat output to a comfortable temperature between 40°C - 45°C. The Shiatsu neck pillow massager can be operated via the built-in rechargeable lithium-ion battery, which provides enough power for a 60-80 minute cordless massage (charging time is approximately 2.5 hours). If you sit in an office chair all day, your back and waist are under significant pressure. This massage pillow can be used to relieve muscle stiffness caused by long hours at the desk. The heated Shiatsu massage can make office life more enjoyable and pleasant.
