I just got it last night and tried it immediately. It was easy to operate and even though its battery operated the level 6 was definitely powerful enough that it felt much higher. The instructions were easy to understand and the fact that they included the batteries and an extra set of pads was a bonus. I recommend it.
I just received my TENS Unit yesterday. Last night I used it for the first time. It felt so wonderful, I didn't want to take it off my back! It really helped me. I wish I had purchased it long before now.
I had it almost for a year and it works great. Easy to use. Has the option to chose massage, beat or need. There are many other different options available (intensity, speed etc). Also wires are long which I like.
If you are in Canada, there’s going to be Custom charges you will have to pay separately.
