I'm pleased with the set overall and enjoyed building it for my son.  Be prepared for a long build time.  I found it helpful to sort through all the parts on a few tables and having a larger table just for building the sections as I went.  In hindsight I wish I had numbered the hardware bags and then numbered the hardware in the instructions to speed up the search for parts.  The wood is stamped so that was easy but there is so much hardware of varying sizes that look alike that I spent a lot of time rereading the print on the bags to make sure I had the right size part.  The instructions are 89 pages long and pretty well detailed but again it would have been faster if the bags were numbered so you could set them out in numerical order and know that in step 1 you need four 1's, four 2's, four 8's, and sixteen 22's for example.
