TENS 7000 Rechargeable TENS and EMS Combo Unit, Four Channel

It is a bit difficult to set and you have to reset it each time you use it which is a little annoying but not bad. It desperately needs to have a backlit screen unless you can turn on at night. To set the pulse patterns and so on and so forth is more than a little complicated as the instruction manual is extremely weak in this area.

Wast of money

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.
