This is a great product for the price.  Like what many of the other reviews had said - the corners of the main pieces were slightly damaged.  I'm unsure if this happened during shipping or at some other point.  Despite this they were hardly noticeable and easy to touch up.  The options were highly customizable from the height to the width.  Also with whatever you want in between.  We didn't feel the need to purchase additional shelving or drawers outside of what it came with.  If we do it looks like they'll be easy to add.  

Pros: Great value
Cons: slight damage during shipping
