I got myself this TENS machine to treat muscle spasms. There is also excellent. The device has a number of programs for the different stimulation methods (massage, TENS, EMS) including a short guide which program is suitable for which type of treatment. Since this is a battery-powered device, the output power is, however, too limited to use the full scope of the device can. The device has, via two separately controllable channels from each other. If one uses but both at the same time and increases the intensity too far, so the voltage collapses and the unit turns off. Very sad, but for most applications ranges from a channel completely. Who wants to use the device frequently, should still get the same additional electrodes. According to the manual this should be changed after 20 treatments. More frequent use is certainly possible, but it will affect negatively on the adhesion of electrodes.
