I needed storage for a large DVD/Blu Ray collection, and I wanted shelves that would not overwhelm the room.  These are just about perfect.  

My only issue is that the information about the shelving says that it has been optimized for blu rays, and they do send you a whole bunch of extra shelves.  BUT the holes for the shelving are not drilled in such a way that you can actually make the entire shelf "blu ray" size.
