This is an XFT-320A Electrical Stimulator/Massager with 28 pads and Acupuncture Pen by XFT!
Unit originally came with 4 pads - there are an EXTRA 24 PADS included with this purchase,
Tried once - I bought it for basal joint arthritis in my thumb and since I have to use 2 of the pads, there is not enough room in the area I need it in. It is for a larger area than the base of the thumb. Otherwise, it works great and has a lot of features.
