These look amazing and are easy to install.... however, they peel!!  I wanted them in my kitchen as a backsplash for a very small area. They have no problem sticking to the wall, but they will not adhere to another sheet.  I even ripped it out, cleaned the wall (just in case), and purchased a new batch.  Same issue.  Even with superglue, they do not lay flat.  I love the look, but Im going another route and having a contractor install a tile.  Its not what we wanted because we were looking for a DIY solution but I dont have time for a peel-and-stick that wont stick.
