Digital Pulse Massager 3 AB offers a battery-operated muscle stimulation system that helps relieve minor muscle aches and pains. This pocket-sized pain fighter features multiple settings and modes, a compact design, and a rechargeable internal lithium battery. The unit also features a brightly lit LCD screen for easy reading. The different massage modes and soothing haiku mode stimulate tense and sore muscles by sending pulses through the included electrode wires and adhesive pads. The massager's AB feature also allows for ultimate control--each of the 2 output channels can be on different intensity level settings at the same time. Additionally, this combo set features a pair of massage sandals that are designed to target pain on the feet. The sandals are universally sized and feature an adjustable Velcro strap.
