This thing is awesome!
Bought it for the wife as an anniversary gift and she totally loves it.  She uses it for her lower back and gets a lot of Oooo's and Ahhhh's from her.  It works nicely because you can just lay it over your back while lying down and it provides a very firm and satisfying thumping massage.  No need to strap it down or pull down on it.  She always laughs when using it because it feels like an actual person's hands thumping your back.  I use it for my shoulders and it works great.  Also really good for the legs and calves.  I just bought another one as a gift for the parents.  At the current price, it's a steal!!
