I bought these for my walk-in closet.  They are really well made, very heavy duty!  The edges have a nice clean finish and the white is really bright white (unlike other brands with have a yellowish tone).  They came in two boxes for each cabinet, and it was a bit confusing at first which boxes went together since I ordered two (which is 4 shelving units), but after the first one I put together I was really quick and easy. 

Pros: Heavy duty, good quality, sturdy
Cons: Need two people to move each box very heavy
