I'm using this primarily as a display case for some action figures and miniatures and it works great. The sliding doors allow it to be used in my small bedroom because the overall footprint is very small.
Tips:
1) use a vacuum to clean off the styrofoam bits off each piece.  
2) read the instructions two steps ahead to make sure the pieces are set up correctly for the next steps.
3) glass doors are removable and you need to remove them to place the shelves
4) weighs around 35-40 pounds when put together. Build it close to where you're going to put it.
5) it is not very sturdy until you screw the backing on.  
6) the shelves fit small books, but not the full size hardcovers or comics.

I found it an excellent deal for a nice piece of furniture.
