I used it for 20 minutes last night for the first time. Second night, the machine will not turn on. I should have researched more reviews. It sucks. Now I have to go through the return process which takes time out of my work day.
Official TENS 7000 Electrode Pads - 2" x 4" - 16 Count
Very easy to use and last a long time
I use my tens to help me handle the pain in my neck, I have had a spinal fusion on my neck and also two back surgeries. Due to other complications not of my neck or back I can not have any more surgeries. The tens helps me manage the flare ups of pain I have, yes it is not a 100 percent cure but I will take what relief I do get.
It works just as advertised. No problems.
