I was thinking about installing glass tiles for my kitchen back splash but since I cook more than I would like too, I didn't want to clean, scrub or treat the grout.  So I opted for these assuming that they would appear cheap.  I love they way they look.  My husband is happy that he doesn't have to paint the wall in the kitchen and no grout to clean.  They look strikingly beautiful and shine just like glass tile. Simple clean up with Dawn and a sponge.
