Easy to use, clear instruction.
I get back aches on occasion and see a chiropractor who uses a tens unit as part of my treatments. It is a perfect kit to have to available in between treatments. I like the ability to use one or two channels to have more stimulation. I have used it a few times since receiving it and am happy with the results it provides. I like the compact size and different programs for different areas. Also to be able to adjust the intensity to match the stimulation that feels best to you. All in all I am very satisfied with this and would recommend it to others.
