This is more of a grill drape than a cover. Here in Arizona, with minimal rain and wind, even the slightest breeze will lift this off the grill. I have taken to weighing it down with blocks and bricks to keep it in place. Bought to replace an older style Weber cover, made of heavier material that had worn after years of use. An older style cover used on a companion grill remains in place. This new design does not do its job. And Weber says there is nothing it can do.
