Unfortunately, this did not work for me- I have old ceramic tile that is terribly dated and wanted to update without ripping out old tile.  The old grout lines were deep enough to show through no matter how I tried to apply the tile- the sheets are thick enough to handle minor surface variations, but not significant grout.   If you have really small tiles and shallow grout lines or on a flatter surface/wall- these would look really great.   It's not hard to install- just take your time measuring, cutting the tiles straight, and aligning/positioning the pieces carefully and using a straight edge tool to smooth out the tile so no bubbles show up (it's one large sticker and the bubbles can get trapped underneath).  Easy and no mess.  From an angle and photo where you can't see the surface that well- it actually looks nice- but in person, it didn't look great- see photo.   Wish this worked for me.   Easy return with Wayfair, so I'm hoping there is another option I can find here.
