Have any of you bought and tried using this cookie sheet from Heirloom Cookie Sheets? I heard good things about it on a food blogger site, that it's 100% food grade stainless steel and non-toxic. I really like this. It's American made too which is a plus and it looks like it bakes cookies evenly no burning. I am considering buying one for myself and maybe my mother and aunt for Christmas. But I am just wondering if any of you own one and what your thoughts are on how it bakes and how you like it before I make my purchases. I watched the news story on their website and read some of the news are articles they have posted. It seems like a good product. Any feedback?
