After a few physiotherapy sessions and yet permanent tension due to my many desk work, I bought this Nervstimulator me out of sheer desperation. I'm excited! My nodes in the neck muscles are barely noticeable. Have the device left to also test other family members and with them it has helped with back pain. Despite daily use keep the pads still very good. I would recommend this device to anyone suffering from pain or tension and it would also buy yourself any time!
