Bests & Worsts Reviews from Amazon

Love this thing. Great battery life. Very strong current. Pads are rated at 30 uses each but, I have found them to last longer although they don't stick quite as well after a while but, the pads are not supposed to last forever so, no problem there. It took a few 'sessions' to figure out where to place the pads and different modes to get the relief I needed but, once I found the right combination, it was awesome. I have sciatic issues and I found some charts online for where to place the pads but, none of them were helpful, and I was thinking of returning it but, I'm glad I kept at it because now that I figured it out, it's totally worth the money. I bought a major brand name type of device like this once at the pharmacy, and it was useless. I'm not sure if it was because the pads were a fixed distance but, all it did was burn at the spot where the pads made contact. On a separate note, this is listed as a TENS unit, as apposed to a NMES unit (you can do a web search to find out the difference, basically the TENS is supposed to target nerves, and the NMES targets muscles) but, you can totally get this unit to make your muscles contract if you just place the pads in the right places. In all fairness I haven't used an NMES unit so I don't know if it would work better for muscle contraction, or even maybe this unit is not calibrated correctly so it is bridging both frequencies.
