I purchased this pergola to cover an area on my deck that had too much sunshine.  The west sun beat down on my deck and house causing the area to be very hot.  This pergola fit the space that I needed perfectly.  It provides adequate shade and withstands the 25mph breezes we have most of the time.
As a matter of fact, we had a 100 mph windstorm come through a few days after I put it up.  Other than some of the piping coming apart on the canopy, there was no damage.  I was able to slip the piping back in place easily and have had no other issues.
