Extremely easy to install and it sticks very well to the wall.  I will say if you have an area that has a wall/cabinet flanking the tiles they look much better.  My kitchen cabinets end at an odd point in the wall so the backsplash just ends and needs finishing on the sides so it doesn’t look cheap.  I bought some small trim at Home Depot to help finish it off.  Because of this, you can tell it’s not real tile.
