Query: Okay, but the heat's not hot

It's not all that I expected: the heat doesn't seem to ever even get warm. The heat is timed for nine minutes, and after that time I still don't feel any warmth on my back (it isn't designed to warm the thighs). I bought this, expecting a warm massage, but it doesn't deliver on that expectation. The massage is at several specific points. As long as that is what you expect, it's fine. Don't expect the effect that you get from the ones that have moving rollers - the roller types cover a larger area, and are more to my liking. But this unit's massage is okay, since it's what I expected when I went in. I just wish the heat was at least warm.
