I bought this cover about a month ago. It is lighter in weight than my previous Weber replacement cover. It is easier to put on. I have not had the problem that the cover blows off in the wind. The velcro straps prevent that.  It is just about an inch too small for a Weber 1100 so not as neatly fitting as the old one, but because of the lighter material this is not a problem. My Weber 1100 is 20 years old and looks like new. I have replaced the burners and the flavorizing bars twice and it keeps doing its job perfectly. Weber is a high quality product.
