Best adhesive ever; worst mirror ever. [SEP] I've 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 doesn't seem to matter, because it just sticks and stays there.  Unlike suction-cup systems, this has NEVER fallen. It hasn't become brittle. It isn't nearly as limited in the places you can find to get it to stick.  In short, it is perfect!!<br /><br />Except 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 option.<br /><br />So, while this is quite honestly the best mirror I've ever used in my shower, I'm still looking for something else...
