The shelves are a good size.  We purchased the white finish, it is very shiny and makes the shelves look almost like plastic.  The installation was a bit difficult.  Make sure to NOT use the drywall anchors included in the package.  Purchase toggles with a long screw as the mounting board is quite thick.  We found the regular 1/4 inch drywall anchors and screws they came with did not work well.  They include white stickers to go over the screw holes where you attach the shelves to the mounting bracket.  The stickers were marked up due to being packaged with the wood screws so do not exactly blend in perfectly on the shelf.  The main issue is one of the shelves had 3 cracks extending across one end (of course the end that is facing out to be seen not the side facing the back wall) so looks cheap and ruined already.  I am going to try to fill it in the cracks but doubt it will look new, but just too much of a pain to send back.
