Pros: Seemed to be decent quality shelving.  Heavy. White laminate not too thin.  
Cons: a BIG project, including lots of gluing of dowels to hold stuff together.  The instructions were nearly incomprehensible.  The caps for the top of the metal bars were very flimsy plastic.   There were little round white stickers to cover lots of holes. 

I actually gave up before I event started, and am gonna give it away.  (mostly because I decided I didn't like the white. )
