Great Unit. The adhesive on the electrode pads (2x4 inches) really stick well!!
Ordered the TENS 7000 unit, for my Fiance's pain,  in his lower back, his shoulders & his neck.(from an old jury) It does bring him some pain relief. The unit is compact, easy to use & the electrode pads have really good adhesive on them. Make sure to order the Tens 7000 electrode pad holder, to store your used pads in, for additional use, which is very handy.
