Really great corner bookshelf, and relatively easy to build. My only complaint is regarding the instructions. 

Not only did they have multiple typos (in big, bold text, no less) and it had this requirement you not screw in screws completely until told or at the end. Which in theory would make sense, except they never explicitly stated when to screw in screws all the way. So strictly following their instructions, you wouldnt fully tighten the screws until you are sticking the whole thing together, which wouldve made a huge risk of the shelves falling apart. 

As you probably gathered, I ignored this instruction, tightened screws as I went along, and the build was totally fine. 

Either way, great shelf. Highly recommend.
