This bookcase was, overall, easy to assemble by myself and is the perfect size for what I needed. I kept one long side off and put it sideways on top of my crafting cabinet with drawers, to use it as a little hutch of sorts. For most, this may be a bit smaller than expected, but for my purpose, it fit like a glove. 
The one thing I dislike about it is that the screws dont lay quite flush to the sides, so they stick out a teeny tiny bit. Since Im using it on its side, the screws are a little in the way of a perfectly flat surface. 
Yes, its cheap material, though sturdy enough for basic use. If you want solid wood shelves, then spend more money on something else. For cheap storage shelving, this does the job.
