Easy to cut and apply.  Can peel and re-stick if they are lightly set in place on painted surface but once you press firmly in place they may take paint if you try to remove.  Would work great over tile and would remove easily.

Pros: Quick, easy alternative to tearing out a tile backsplash and re-tiling.  
Cons: Wish there were more color and tile size options.  The possibilities could be endless!
