At first I was very happy with this, but after a month, it all started peeling off.  Have no fear I thought I figured out the problem, which was to overlap the pieces.  Unfortunately that was not the case.  Pieces still continued to peel away from the wall, even though there was plenty of stickiness on the paper.  Well 5x later, it won and is now in the trash.   My walls were cleaned and prepped, followed the directions and gave it several try's.  NEVER AGAIN!!!  :(
