Installation is pretty simple, the peel and stick works well.  Smoothing with a wallpaper tool (as suggested on the instructions) was not a great technique as it does cause scratching, I mostly used my hands to smooth it in place.  The reason I am giving 3 stars is because of the repeat. There is a lot of waste and I really had to piece together some small bits behind the vanity to make this work. I ordered an entire extra roll and still ran out.
