Visually it's really what ago. By comparison, for my Weber OTG I had an out of gray plastic film, while still holding, but visually not really work anymore.
Why then (only) 4 stars? The surface is black, matt and slightly structured. And this structure holds eg birch pollen etc. firmly tidy. The dirt can not even so just wipe or sweep. It really needs her a cloth and water, so that the cover is clean again.
Yes, it costs a lot of money. But this is unfortunately in most Weber stuff like that.
My conclusion: The cover is meticulously crafted, looks good and satisfies your job perfectly.
