Pros:  Convenient size and nice color.  The unit seems stable and a good weight, so it will not topple over easily.  The top shelf/cover is a good idea and is a nice styling feature. (Many shelving units are open at the top.) Overall, the bookcase looks as if it will last for a while and it is useful to have a folding unit so that it can be moved or stored.

Cons:  The unit has taken enitirely too much time and energy to assemble.  One shelf has cracked along the natural grain of the wood where the screw hold was drilled.  (I'm sure that it can, and will be replaced). However, the major difficulty is in assembly.   As the owner of other folding bookcases, it is simply much easier to purchase the ones that you simply unfold right out of the box.  This was much more of a hassle than it seemed from the website.    

Pros: Pleasant styling, solid, portability.
Cons: Assembly is too complex.
