I bought 4 shelves for on my bricked fireplace wall.  I put two one on top of the other, and the other two side by side.  I bought the black, as they are near my new TV, which is black and it looks good.  They are a good quality and I have no qualms about putting anything on them.  They come with templates and screws and anchors.   

Pros: great value, easy assembly, just the right size, comes with screws and anchors
