I’ve been using this for a few months on my husband who’s had a stroke and it works well. Also i use it on my back when i have aches and nots.

Works exactly as I was hoping. Easy to hook up and control. Arrived earlier than they said it would. Have recommended it to a few friends.

Very nice machine. Has been very helpful after injury

I use this on my back. If you use it any place else, YMMV.Having 4 outputs for a total of 8 pads is great. The unit applies full output to both channels, it’s not cut in half if you use both channels. There are 2 channels, each with 2 outputs, for a total of 4 outputs. 2 pads per output, hence 8 pads.I wear this all day and it’s like constantly getting a back massage.The wires are very long. Too long really. But too long is better than too short.

The instruction manual is far too small to read and lacks sufficient detail as to its proper use.It wouls be helpful if the distributor posted a full sized, detailed instruction manual on their website.Otherwise, the TENS appears to work fairly well.

I'm recovering from my second back surgery and as I write this I'm still in rehab, after two months. I tested this device exstensively, compared to four others, and although it was ok for my needs it was not powerful enough and did not have enough different modes. The battery life is nt very good and in my situation to make the re-connect from brain to muscle, very common with back surgery, it's didn't have enough power, the controls are small, no backlighting on control panel for night use. I would suggest this unit for chronic pain and deep muscle massage, but not for serious injury recovery.
