I have not had the chance to use these as yet, but so far I like the development, texture and look of them. They are going to be my back splash behind the stove. They will be replacing takey tin diagnole squares that are hard to clean, fall off and look awful. 

Pros: Masaik 1 x 1 tiles: Peel and stick have me nervouse but these look good and I hope they will stay on the wall for a long time.
Cons: Masaik 1 x 1 tiles: Peel and stick scare me hopefully they will have a long life
