This Neck Gun Body Massager comes with an ergonomic U‑shaped design and extended handle that matches the 120‑degree curvature of the human spine for self‑administered deep‑tissue massage. It has four interchangeable massage heads and five speed levels, which allow precise targeting of the back, neck, shoulder, waist, calves, and other muscle groups. This device serves as a self-recovery tool by alleviating pain and swelling, enhancing blood circulation, breaking down muscle fascia to improve elasticity, and increasing the range of motion.
