Query: Best yet

Bought this on the recommendation of Dec. Gourmet review of cookie sheets. It is the best one I've seen yet. Using sheet pans doesn't work for fragile cookies, and sheets need to be shiny for good browning. This one is large, shiny and appears to not warp. (only had it for a month) Easy to clean and cookies release easily.
