I love the size and color of these tiles.  I bought them because I wanted to change the kitchen back splash in the home I just bought but didn't want to rip out the old. The issue I am facing is that the tiles FALL OFF during the summer time when things get a little hot and humid. I woke up at 4am to crashing breaking glass sounds and thought I was being robbed. Nope, the tiles were falling after having survived the winter (when I initially installed them).  Again, I really like them but they need to be used somewhere nice and cool all the time.
