We bought this a couple years ago trying to put some shade in our back yard after taking out a tree.  It's become so much more.  It's where we want to spend all of our time in the spring/summer/fall.  We leave the frame up all winter and it has yet to show any wear.  The top canopy does need replacing after two seasons, but that's typical.  I chose this particular model because of the side fencing for stability.  We live close to Lake Michigan and can get some pretty strong gusts of wind and we have not been disappointed.  It's stood up to 75+mph gusts with the top on and hasn't twisted or flown away.  We don't have it anchored beyond the stakes that come with it.  Impressive!
