This Review Title is Incredibly strong suction cup or overly weak mirror? and the content is: Put this up at 7pm on an over the door mirror.  I guess that was mistake number one.  Please see picture for what the whole house woke up too at 4:30 am.  We used it once before the mirror broke.  As far as functionality, it did exactly what it is supposed to do. It held the hairdryer perfectly in place and I was able to adjust as needed, although it is a little stiff. The arm is not long enough for it to stick to our over the sink mirror, which may be stronger, and would require my daughter to have sit on the sink to use.  So...not sure where to go from here since other reviews say it doesn't stick to much else but mirrors. I can't give it any less than three stars because if given the perfect circumstances it does exaclty as it is supposed too. I can't give it more than three stars because now my mirror has seven years of bad luck!.There are other information for this review, one is This reviewer did purchase it and the other is 2 people think this review is helpful.
