I purchased the Smart Tiles for my vintage travel trailer. I originally wanted glass mosaic tiles for my backsplash but realized the trailer wall could not support the weight. I found the Smart Tiles on someone’s blog and thought I would try them. They really worked well! And their very forgiving as far as placement. The only advice I would give someone is to paint the wall a shade similar to the “grout” lines. I was careful but there is one spot where there’s a tiny gap and you can see the white wall behind. It’s not glaring, but I know it’s there. If I had painted the wall gray, like the “grout” lines of the Smart Tile, then you wouldn’t see it at all. I would totally purchase this product again.
