This item is complete. This is the device that instantly emits cold or heat to treat muscle aches and joint pain. Aluminum head heats to 110º F or cools to 40º F--the ideal temperatures for thermo- and cryo-therapies--in 45 seconds, relieving swelling or facilitating blood flow to help heal injuries. Eliminating the hassle of being tethered to a heating pad or refreezing a cold pack, the device is smaller than a television remote and its head swivels 90º, allowing you to easily position it against your body. A toggle switch changes it from heat to cold application instantly. Requires four AA batteries (not included) 6" H x 1 1/2" D x 3" W.
