Title: Shiny but warped
Review: As noted by other reviewers, these warp badly -- pretty much anything over 350 degrees, and even 350 is dicey. Not necessarily a problem if you are only using for cookies, but not useful for anything else!One (better) alternative is Chicago Metallic professional-grade large jelly roll pans -- available on Amazon, but also from Chef's Catalog (2 for $30) and at World Market (Cost Plus) stores. Costco also used to have a set of 3-4 professional-weight cookie/jelly roll pans even cheaper, so keep an eye out for those!
