I bought this a few months ago to replace my old canvas BBQ cover. The installation was very straight forward with great step by step instructions. Everything about the gazebo is of the highest quality, I expect this to last a long time.
I added a permanent back for privacy and weather protection and also added removable sides to protect from the cold and snow here in Colorado during the winter; these will be removed for the summer.  
Just a great product overall and now I can grill in any kind of weather and stay dry and warm.
