I searched everywhere for a quality set that wasn't  $2000 or more. So happy I went with this gorilla set. Very few sets are all 4x4 supports and has a 4x6 support beam for the swings. This thing is solid.  I spent 2 days staining it for extra protection and 3 more days for installation by myself. It was a pretty easy job just took a while. Only a couple of pieces didn't fit how I would have liked. Mainly the windows and dormers were not fitting based on the instructions and I had to modify them myself. All pieces were there and the hardware is solid. I had about 100 extra screws and lag bolts left over!!!  Trust me I didn't skip a place where a screw went and even put a few extras in spots. Overall we love it!
