It's good, but you get what you pay for
This is a really good product, but unfortunately does not last. I bought one which lasted 3.5 weeks and luckily broke just before the window to return ended. For the price tag I was not surprised but having read more reviews it seems this product was designed simply to fail. Mine broken away that it started pulling too much amperage. Broke after using it in the car which caused the power supply there to pop the fuse. I tried to use it in the house and it lasted 2 seconds before dying. So it would seem the product likely blows capacitors or something inside.<br /><br />As for the relief, it's great. Especially since I have not in my back right in an area where this works it pretty well. It just doesn't last and I guess you got what you pay for. $22 for a few weeks of massaging.
