The design is really nice. It was the cheapest geometric bookcase I could find (with this desirable color scheme). The quality is alright. The shelf isn't as sturdy or stable as I'd like. it to be. You definitely need a power screw driver to assemble this. The screw hole alignment can be better. 

Assembling tip: Assemble the cubby holes individually as opposed to bottom-up, planning for easy screw driver access.
