My wife and I just finished assembling this swing set in four half days. Our grandchildren were wowed by the result. The instructions were very well written with adequate warnings when specific part orientation would affect a future assembly step. The parts arrived absolutely unscratched. bent or dented ... the result of careful packaging! The only suggestion for improvement I would make would be to replace the size 2 Phillips head slot screws for the climbing wall and roof attachment with screws having a size 3 Phillips head slot. It was difficult to apply the necessary torque with the smaller slot.
