I bought two swing sets. It took myself and one other person to build both sets about two days. Kids love it, very durable and well built. Only one problem occurred during assembly. The screws provided to assemble to rock climbing tower and roof were not manufactured correctly. The cross head was too small for a drill bit to grab and then sink the screw into the swing frame. I had to run down to hardware store and buy self-drilling sheet metal screws to finish the job. Other than the one problem, the instructions were very easy to follow and no missing parts. I love it!!
