Assembly was easy and the finished product is all I could have asked for! It's heavy and sturdy-feeling, and the bottom dividers have already been used as the site of at least one epic feline-on-feline ambush.

Would have been nice to have had a "hinge bumper" on both sides so it doesn't feel like it's crooked when raising or lowering, but I may be able to locate a similar one at a hardware store. 

Looks great with the new bookcases I purchased and assembled earlier this year.
