Assembly took me about an hour by myself, which was longer than I expected. For the most part, the assembly was smooth. However, one of the nails had a flat head, so it could not be screwed in all of the way. Unfortunately, there were no extra nails, so I left it in partially screwed in (from what I could do with my hands).

My other complaint is that one of the smaller boards had a small chip in it.

So not a 100% perfect product, but the flaws are tiny enough that I don't think many will notice.
