Poor Quality
Poor quality.  I bought in Feb 2018 and it's the end of March, the wires are already bad and cause the tens to go on and off.  I'm hold the wire in the onn position, by grabbing it between my fingers and jiggling it around and smoothing it out, then put a binder clip on to try to hold it in place, but it still goes in and out.
