This TENS machine uses a very small electrical current, which passes across the nerve carrying the pain signal to the brain. This affects the ability of the nerve to transmit the pain signal. If the brain receives no signal, you feel no pain. The unit has six different treatment regimes which are automatically controlled to give a measured treatment of 40 minutes. It is supplied with a case, two contact pads, two cell batteries and operating instructions. Total weight 305g (including case). Dimensions of controller: 85 x 40mm (3 x 2 Inch).
