By the way, it came today and I've been wearing it for about 6 hours. Not much to tell yet, except that it burned 2 little holes in the skin of my abodmen - it seemed convenient to pop it in the waistband of my pants to hold the electrodes (2 pennies) against my skin. Maybe that was the wrong place to put it, I have to write to Don & ask him. It seems OK everywhere else I've tried it. Definitely feelign some electricity. Time will tell, I guess.
