Relaxnecker Neck Massager:- uses a combination of mechanical and heat-based therapy to target muscles in the neck and shoulders. Here’s how it works in detail. The Relaxnecker is equipped with rotating massage nodes that simulate the action of a professional massage therapist. These nodes move in circular motions, kneading the muscles to release tension and reduce pain. Depending on the selected mode, the nodes may also tap or vibrate, offering additional relief.
