This pocket-sized pain fighter features multiple settings and modes, a compact design, rechargeable internal lithium battery and 2 output channels. The 16 different massage modes stimulate tense and sore muscles by sending pulses through the included electrode wires and adhesive pads. You can independently set the modes of each of the electrode channels by using the 2 controls on the unit. The Belt Combo Set also includes an adjustable belt that can be worn over your abs to electronically stimulate the core muscles. With regular use, the PCH ab belt will tone upper abs, lower abs, and obliques, as well as reduce the appearance of stomach fat and love handles.
