I give the topper high marks. Any problems with it are mine. I have over 600 sq in of cooking surface on my Weber S330. This thing takes up most of that. So I can't, really, be doing steaks or burgers while grilling veggies, mushrooms, kabobs or whatever. Its all bright and shiny appearance is gone now. I sprayed my veggies with olive oil and now it is all brown. Even after cleaning. But then, what stays new looking after having been on the grill. Now it looks all used and stuff. And I like it. I would recommend this product to a friend with a larger grill surface. Given my 'druthers, I would buy again but a slightly smaller version.
