I have a tens 3000 and got the 7000 as an update
Appreciate the comfort that comes with using the new TENS 7000 Electrode Pads.
My physical therapist demonstrated a medical-grade TENS unit for my chronic back pain. He recommended I get a portable model, specifically the TENS 7000. It is a little complicated to use for the first time, but after that, it's reasonable. It really works well, even after only a few-minute session. The instruction manual tells how to use it and how to adjust it, but doesn't really tell you what settings to use for different sorts of pain or areas of the body. However, there is plenty of guidance online via video demonstrations.
