I have another hair dryer holder, but it's attached to a cabinet and not easily removable. I bought this for our vacation home. It attached to the mirror easily and has stayed in place for days. I do use a light weight dryer in it. It comes off with some effort, which is good, as you don't want it to come off easily. The arm is long and bends firmly, so also stays where you move it. Have not tried it on a wall as the mirror is the smoothest surface in the bath room. Would buy again!
