So I just got my HDR last monday. I did a 8 minute treatment I put my electromagnet next to my AC it shorted it out. I unplugged it. Turned it back on. Then did the same thing beyond a foot. It shortened it out again. Unplugged it and turned it on and started working again. I noticed when I was watching the Patriot's Jaguars game It was 5:09 as I was texting a friend it went to 5:29 I don't fall asleep that quickly. I basically turned my head. My phone even has proof. I plan on doing a treament thursday. Gibbs called me after I called him panicking that it worked. He said he was happy he was getting results. Buy one now, because they work wonderful, and that is a myth that electromagnet affects my pacemaker. I was nervous using it the first time. But as I get used to it I become more proned to it. I also get foggy eye's. when I come back to normal.
