We live in the Chicago, Illinois, area where summers are hot, with intense sunlight, and winters are bitter, with high winds and tons of snow and ice.
This canopy for the few dollars it cost weathered all those conditions for 4 years. It is finally time for a new one. The frame is still okay, but the cover has been brutalized by the heat and cold. It still functions, but it is looking a bit worn. There have been winds in excess of 50 miles an hour when the canopy shook and screamed, but it withstood it all. A great bargain from a super company.
It is a perfect shelter that we use over our hot tub in the backyard.
The initial assembly is difficult to an extent. Because it is so tall, there needs to be 3-4 people assembling. Anchoring it so it can withstand the wind is another "decide on your own how best to do it project." And, lastly, it would be greatly helpful if there were a couple more cross members from side to side to help support snow loads. After a heavy snow, the canopy gets loaded, sags, and if you don't go out and knock the snow off, the canopy would surely collapse. A couple extra cross members would hold the top straight so the snow would be more likely to slide or blow off.
