Available only from Hammacher Schlemmer, this is the knee massager that uses heat, vibration, and air compression to help reduce pain and stiffness. Ideal for those who suffer from arthritis, injuries, or other conditions, the compression wrap uses heat therapy to help improve blood flow, reduce inflammation, and relieve joint pain. It also employs vibration massage to sooth muscles and air compression massage that can be operated independently or with the heating elements for a full triple therapy treatment. Charges via USB. Adjustable hook-and-loop fasteners fits most knees. Suitable for use on either leg.
