What coudl be better: I found it very difficult to peel off the backing -- actually thought there was no peel-able backing and called Wayfair and the supplier for help. The "tiles" are not perfectly square; they are more of a rectangle -- very small difference but enough to mess up one's measurements. Not a good choice if you will be viewing it up close.

What works well: Very  easy to install, and to re-position if you need to do so. I ended up installing it on the risers of my indoor stairs, and viewed from a distance it looks attractive. Nice splash of color without being garish.
