I have two early impressions of the Big Magic PEMF mat. I tried it propped up behind me when I am sitting at my computer, it has definitely helped reduce the ache I get in the shoulder blades area of my back when I am tired from standing up a lot. Reduces the achy feeling a lot. Then I let my husband try it, we put it so he could lean back on it when sitting at the table for breakfast. He has had very annoying “prickly” feelings on his back since he had an outbreak of shingles a couple of years ago.
The Big Magic seems to stop the “prickles” when he is sitting leaning back against it. It also seems to have some lasting improvement that extends during the rest of the day. The prickles are usually back the next morning, but the Magic helps again.
