Shelves are just OK.   Each shelf had a notch at the end that serves no purpose and was probably an accident in the manufacturing process.   Also, it was very difficult, in a couple of cases impossible to screw the screws into the metal wallboard pins.   It took me much longer than anticipated to hang the shelves.   They look OK now, but the quality was not the same as the Guinna Iron Cube Bookcase that I purchased.
