Quality materials, well designed, sturdy swing set. BUT, if the company would invest a few hours in writing instructions it would save thousands of hours in customer assembly time. It really took 2 experienced men 12  hours to assemble! Most of that was interpreting instructions, and often having to go back and undo something that was a very subtle detail in a picture. The perspective drawings are deceptive and require intense attention to every detail. We had to fix some overlooked details by re-drilling holes. Once it is done, you feel like you accomplished something, but it COULD be so much easier. Pay someone to assemble this for you!
