I really love this thing. The only reason that I did not rate all 5 stars is because when I use the heat option, it becomes a little louder. Other than that, I am able to massage my feet for as long as I want to while watching t.v. without turning the volume up. The heat level is just fine, it takes a bit to warm up but never gets too hot. I wanted a nice foot massager that was not too loud or clumsy, and I have found it in this one.
