Well…finally, I got the stuff I ordered from amazon this afternoon and the first thing I did was put the heating pad on my back and I think it’s working…haven’t had a seize up of the muscles since I had the thing on for a half hour and I even went out to shovel the snow so I guess we’ll see in a little while if I can deal with the pain I have left…had the thing up to 160 degrees and it felt pretty good…I really like the digital readout on it, too…the beard trimmer is pretty nice and I’ve already trimmed my beard once with it and it’s so nice to not have to hold the cord in the trimmer like the old one…so, a nice 40 bucks spent and it appears worth it…
