Review on Rechargeable Dual Channel EMS TENS Unit Muscle Stimulator With 48 Modes, 14Pcs Reusable Electrode Pads And Continuous Mode Electronic Pulse Massager - Storage Pouch/Pads Holder Included by Scott Chen

This seems to do the same thing I was getting at physical therapy and is pretty easy to use. I've just used the basic mode that I would get at PT, and it seems the same. It has a lot of different modes (kneading, acupuncture eg) I have not tried out, so I can't speak to them but hope to at same point. It's a little harder to put the pads on yourself than I thought it would be, but instructions are good and the charging feature is nice. Customer support seems very responsive. I haven't needed it as much as I though, which is a good thing!
