Some people have noted that the part that hangs over the door is quite a bit wider that the door width - it is, but I put those sticky cushion things in the inside of the overhang and it works fine.  I also put the rubber shock absorber sticky things on the towel rack side where it would have rubbed against the door and that seems to help keep the towel rack in place.  The towel rack works fine and looks nice and frees up my wall space from having to install towel bars.  I'm happy with the product.
