I've been using the GS unit and am going to get the PC hopefully pretty soon. The GS really does suck though, the machine however is pretty cool in that it has it's own timer. I had the RA Fischer a coupler of years ago and that hurt worse than the Idromed.
Have you guys had any success with the machine yet? The first night that I used the GS my right hand, which was in the positive polarity actually was harder to get sweating than my left. Then today after two days of treatments I noticed that my hands took a lot longer to get sweaty and the sweat started out in little beads instead of the whole hand just instantly becoming all wet. But tonight I used the machine again and for some reason my hands seem to be sweating more, also what's the deal with the inconsistency of the pain of the polarities? The first 2 treatments the positive pole was pretty painful while the negative wasn't, now tonight it reversed and I could barely feel the positive pole while the negative hurt. I don't get it.
