Very good quality set, from wood to hardware to swing accessories, except for the chalkboard vinyl.  Hardside board of some type of weatherproofing would have been nice.  All predrilled holes in various boards, etc. all lined up well, and there are plenty of them! I recommend having an isolated area where installer can lay out all bags and boards in some sort of order.  Open the screw bags with a small slit to only take out what is required for whatever step being assembled.
