This is the cordless massage gun that uses heating and cooling heads along with deep tissue massage to loosen muscles and speed recovery. Its powerful motor generates deep piston-like percussions to deliver an intense massage that penetrates deeper into tissue than common vibration massagers. Its six interchangeable heads include a heat attachment, cooling gel attachment (place in freezer before use), a silicone ball, and three acupressure heads (cone, flat, fork). It has six levels of intensity/speed, quiet operation, and a lightweight, ergonomic design that makes it easy to target any area of the body. Charges via USB-C. 5 1/3" L x 2" W x 5 1/4" D.
