I wanted something different for the sides of my fireplace in the new house we just built, and I didn't want to go permanent with built-ins.  This perfectly fit my needs.  I love the different sized openings and sturdy construction.  My husband put two of them together in less than an hour with no assistance.  

Pros: great value, sturdy, unique, easy to put together
Cons: white stickers to cover screws don't stick well
