Double-Sided Electrode Gel Pads 8-Pack, 1.5" x 1.5" replacement gel pad...for TENS, EMS, electrotherapy devices, and especially for Dr. Ho Systems before 2011

Universally compatible for any squarish electrode that fits a 1.5" x 1.5" replacement gel pad...for TENS, EMS, electrotherapy devices, and especially for Dr. Ho Systems before 2011, since you can't get these replacement pads anywhere else! Just remove old gel pad from electrode, electrode itself needs no replacing. Trim with scissors if needed. NOT for electrodes with wire embedded beneath the surface, or with no removable gel pad component, such as with newer Dr. Ho Systems (2011 & later) Quality re-usable adhesive, similar quality to original Dr. Ho.
