I had just purchased a brand new Weber propane grill and ordered a cover on-line for it. I am so pleased with the cover.  It is of a softer material than other covers I have purchased in the past that over time get brittle.  It fits my grill to perfection.  I also like the feature of the Velcro straps on each side so that it can be strapped tight around the grill so it is not affected by the wind.  I have had previous covers blown off in a wind storm.
