This heat wand also has 2 powerful magnets embedded in the treatment area to help enhance the relief of pain. Wand is angled to make difficult areas easy to reach as you manually massage away those aches and pains. Also great for your back, shoulders, neck, legs and feet. Approx. 15" long with 6-ft. power cord for heat only (not a powered massager).
