Query: No power

I bought this for my husband because his feet are very rough on the bottom. I specifically ordered this one since the head was bigger than the other ones I found on line. I tried it on myself first. It has NO power to it at all and if you put any pressure on it, it will come to a stop. After a few seconds with it on, it started to smell of burnt plastic.
