Great product- very easy to use as long as you have a smooth surface. I removed a previous solid Formica backsplash and installed these in a day. However the part of the kitchen that we expanded to, where we were placing the tile on the slightly texture wall, didn’t stick. One by one they would fall off over the next few weeks. This was actually and an easy fix though- we just put some clear silicone on the back of the tile and boom totally secure.
