1. [Simulated human hand design] The upgraded neck and shoulder massager uses kneading acupressure massage technology to simulate the hand movements of a real masseur to deeply relieve muscle tension. From the neck to the trapezius and shoulders, its six massage heads simulate real people's kneading, pressing, rolling and patting techniques to reduce stiffness and eliminate muscle knots. Two adjustable massage intensity levels are provided to meet your needs. 2. [Fast heating] In just 10 seconds, you can experience fast heating and feature two adjustable temperature settings (104°F/120°F). This heated neck and back massager helps promote blood circulation, improve sleep quality, and includes a 10-minute automatic shutdown function for increased heat. 3. [Hands-free design] The ergonomic wearable design of the neck massager allows free movement during use, which is different from traditional massagers. Whether at home, in the office, in the car or traveling, the adjustable strap ensures a perfect fit for all body types. For a more intense massage, simply use the hand-pull method to increase the intensity. 4. Battery life This wireless neck massager can be used daily for up to a week on a single charge. It uses a USB Type-C charging port and can be wirelessly charged without connecting to a power source, allowing you to enjoy a relaxing massage anytime, anywhere. The small size makes it easy to carry and can be put into a regular-sized travel bag, gym bag or carry-on luggage.
