Medtronic Neuromuscular Stimulator (muscle stim, therapy)
Medtronic Respond II Dual-Channel Neuromuscular Stimulator. Model 3128. Comes with everything in the pics, two sets of leads, accesory wire, and user manual. I tested the unit by holding the leads to my skin. When I powered it on the "cycle on" light illuminated and it felt tingly. I did the same for both channels. I'm not an expert on these so although I believe this unit to be working correctly, I can not guarantee it.
Thanks for looking!
