I put this tile directly over beadboard.  It took me the better part of a day. I used tile nippers to cut the tile and an exacto knife. It’s real tile, a few price we’re cracked in the box but nothing was unusable. True to specs and very sticky backing. It is true that you can unpeel it to adjust if needed. I didn’t understand how if it’s supposed to be so sticky but I did it. It is very sticky. Nothing is moving. I’m an every day cook and I’ve had this tile up for about a month with no complaints. My husband came home from work the day I did it and remarked on what an awesome improvement it makes to the kitchen. Well worth the price imo to have it done quickly and painlessly. Otherwise, a conventional tile backsplash would still be on my list with no check-off date in sight. Grouting tile is not my forte so this really got the job done for me. I’ll use a sanded caulk to finish the edges and probably seal the tile because it would stain otherwise but I’m very happy with the results.
