Just bought my TENS unit from Amazon and it got here. I opened it up. It's missing a set of leads and one tens pad. I only have three pads and one set of leads so it's missing some equipment. Check your stuff first when it arrives and make sure you register which I'm going to do just after I leave this review. I wouldn't give it four stars because it's missing stuff and for something it's brand new coming from the factory. I think somebody stuck their hands or missed the mark and went to lunch when this was coming through. In either event, I'm going to file for missing parts and we'll see how long it takes them. Also, I can't leave a photo because I pressed the picture video optional button on the menu and nothing happens. So I'm going to leave this review on Amazon. We'll see again what happens.
I just used the unit on my shoulder for about 5 minutes, for the first time.
Afterwards, I raised my arm up to the ceiling. I haven't been able to raise it any higher than just above straight out to the side,for years. I have no idea how one treatment could accomplish this, but, wow, I'm a believer.
The unit arrived on time and was packed well. I charged it and connected it as my doctor directed and increased the signal strength but was disappointed to learn it was very weak and did not work my muscles properly.
