FENLI’s back shoulder neck massager is engineered to deliver complete, integrated relief across the entire upper musculoskeletal frame. Built with an extended U-shaped chassis housing twelve multi-height 3D Shiatsu nodes, the machine delivers synchronized kneading from the upper cervical spine, across the shoulders, and down into the rhomboid mid-back muscles. Powered by high-torque copper motors, the drive mechanism maintains smooth rotation force under heavy leverage without stalling. Integrated carbon-fiber heating arrays warm target muscle zones up to 42°C, accelerating vascular circulation and muscle tissue relaxation. Manufactured in FENLI’s ISO9001 certified facility, this device carries complete CE, RoHS, FCC, and FDA listings, offering global distributors an ultra-reliable, high-demand full-coverage massager.
