Be careful while assembling!
I have bought similair bookcases in the past...long time ago. I thought the quality back then was poor, because it was made out of compressed sawdust with glue ( composite). But these shelves are slightly less quality of those of long ago. The company has made great strides at providing the pieces with pre-drilled holes with excellent
precision. However, the composite material does not have quite enough glue mixed within. So the material is ever so slightly crumbly. So once you screw in a screw, don't remove it, because if you do the screw will not hold as good. I reccomend that you add a drop of glue into each hole during assembly. The rotating screw locks are made of cheap pot-metal that will snap if you crank too hard on your screwdriver. The good news is the kit comes with plenty of extra screws, wooden dowels, and such.
