My kitchen back splash needed an update and I didn't want to spend a lot of money on it. I am retired now and need to pinch penny's, so I thought I would give this item a try. I am so very pleased with the outcome that I can't even believe it myself. It changed the look of my kitchen, even made my counters (which I also didn't like) look like new. I was concerned because this was a Peel n Stick but the quality is amazing. It is nice and thick and I think will last a long time. I put it right over my tiled back splash with no problem. All I did was wash it with some TSP, rinse it well and made sure it was very dry. That was a week ago and all the corners are still nice and tight. On the corners nearest the sink, I took some Elmers glue and put a thin coating right on the seem. Elmers dries clear, so you can't even see it. Because of the 3D graphics, you can't see the seems from the tile underneath, which I was concerned about. I would highly recommend this product.
