This is a very sturdy gazebo! It deserves 5 stars, but my rating of 4 is based on the intensity of the installation.  You need 4 people for placing the roof panels on!  Two of the 4 need to be young and strong!  We are seniors, it took some time to find two guys who lift!  Except for lifting the panels, my husband and I were able to assemble the entire thing, and even had fun doing it. Friends have already ordered this, but based on our recommendation, included the professional installation.  I will update this review based on the results of that.
