This gazebo is very well engineered and thought out. It will fulfill all our needs for our spa: will keep snow off in winter, mosquitoes out in spring, and blowing needles and leaves out in the fall. It was somewhat challenging to assemble. The very top center piece is tricky so be sure not to bend it. The instructions could explain more thoroughly how to get this top structure up without bending it. Using a power drill helps the assembly process. All in all it is a very well designed and sturdy gazebo.
