this review title is: best adhesive ever worst mirror ever and the content is: i have had this hanging in my shower for nearly two years now and i am completely sold on the adhesive my shower wall is square tiles and this overhangs one tile by an inch or two on each side but it does not seem to matter because it just sticks and stays there unlike suction cup systems this has never fallen it has not become brittle it is not nearly as limited in the places you can find to get it to stick in short it is perfectexcept for the mirror itself the mirror is a very thin piece of clear plastic with a reflective surface glued to the back when it flexes it distorts the reflection but the largest problem is that it is almost impossible to clean unlike a glass mirror the plastic is prey to terrible scratches pretty much any sort of scrubbing will scratch the plastic and reduce it to uselessness the ability to get a replacement would be greatly appreciated but alas it appears that buying a whole new mirror is your only optionso while this is quite honestly the best mirror i have ever used in my shower i am still looking for something else.there are other information for this review, one is this reviewer did purchase it and the other is 31 people think this review is helpful.
