The Zyllion Heated Neck and Back Massager (commonly referred to as the Zyllion ZMA-13-BK) is a compact, ergonomic, and portable shiatsu-style massage device designed to relieve muscle tension, improve circulation, and promote relaxation, particularly in the neck, shoulders, upper back, and lower back—though it can be used on various other parts of the body as well (like calves and thighs).
