Available only from Hammacher Schlemmer, this is the heated massager that compresses the knee joint to help reduce swelling, stiffness, and pain caused by arthritis, injuries, and other conditions. Secured with adjustable straps, its dual air bags inflate and deflate to apply three levels of pressure on either side of the kneecap. This compression technique, employed by professional massage therapists, boosts circulation and increases body temperature to stimulate healing and flush away fluids causing inflammation. Three levels of soothing warmth complement this therapy, and reviewers at the Hammacher Schlemmer Institute commented that both the heat and compression “can really be felt.” With optional vibration mode. Shuts off after 15 minutes for safety. USB plug. Not for use with pacemakers. 7 1/2" H x 6 1/2" W x 5 3/4" D. (1 3/4 lbs.)
