These were beautiful, high quality, thick, and easy to attach to the wall. 
1 thing that I felt needs improvement is the corners of the tiles are slightly bent from shipping. This makes the corners not really stick down completely. Either smart tile should apply some extra glue on the corners, or make them a little more durable to bending/folding/crunching. I had to iron the corners out with my fingers in order to get them to not have corners sticking up on the wall
