Works well and came with batteries
I ordered this to use on my back. I use a tens unit at PT, and I was recommended to try one at home. This unit came with instructions and batteries which is nice. I also enjoy that the two outlets can be set to different intensities. It is a very strong Un compared to my one at PT and found that starting out anything over 4 is too intense for now. I wish it came with larger pads as these are fairly small. Overall, good product for the price.
