Review title is Perfect for tight space on marble subway tile in bathroom (not in shower) [SEP] I did not purchase this on Amazon, but purchased at a local store because I wanted to physically view it first.  I have a bathroom with a sink under a large window.  There is a small space between the sink and windowsill that is tiled in polished marble subway tile (with almost no grout lines).  This is my children's bathroom and I wanted to give them a mirror to help them with brushing their teeth.  I needed something small that did not require nailing or gluing and that would not break and hurt my children if it fell off.  This item pretty much perfectly fit the bill.  My one worry was that it would not actually stick to the slightly uneven marble tile surface.  I was also a little worried that the image would be warped and ultimately unhelpful.  I have had this now for about a year and it has held up beautifully.  It fits in the space perfectly, has a nice modern and clean look that blends into the slightly grey tone of my marble tile and most importantly, stuck without any problems (make sure to stick to clean DRY surface), even with small fingers poking at it.  NOTE that I cannot really comment on the other reviewers' comments about fogging.  It has never fogged up for us, but our placement doesn't really lend to anything fogging to begin with.
