This type of therapy helps your muscles to contract, assisting the release of waste products like lactic acid and aiding your body's normal healing process. The Electronic Pulse Massager is compact and portable, so you can take it with you anywhere. It is ergonomically designed for optimum comfort. The massager includes four attachment pads with electrodes that adhere securely to your skin and remove easily after each therapy session. Requires four AAA batteries (included), the massager features an LCD screen that clearly shows the massage style, intensity, and time remaining. Includes: the TENS unit, 2 cables, 8 electrode pads, 4-AAA batteries, and operating manual. Shipping is only to lower 48 states, US.
