Query: Can't beat the price

I seem to be a sucker for these kind of products. This particular one was a no-brainer based on the $15 price. I've had it a few days and am very happy with it. I would recommend this to people that sit at a computer all day, and tend to get stiff. 2-3 minutes on high will get the blood moving again.
