I was very pleased with how easy this was to put up and how nice it looks! I’m glad I ordered an extra box because I needed it to fill in space at the top and bottom of the backsplash.  It cut very easily with a box knife and even scissors.  The only tools I needed were: ruler, dry erase marker (to mark my cut lines) a box cutter, and scissors.  It’s been up for over a week and nothing has moved or led me to believe it’s not adhered well.  I also should note that I put it on top of outdated painted ceramic tile.  I’ve gotten many compliments.
