I have Baker's Secret brand. They aren't the best and aren't as good as the ones recommended by others who have posted here, but I have a bunch of them and will keep them until they wear out and die. I do, however, have a good hint to share - I used to use parchment paper, but it slipped back and forth when I removed sheets from the oven. For that reason, I tried some of the Reynolds "Quick Release" foil that I had, covering the cookie sheets with that. Works great! It doesn't move like parchment, cookies remove easily, and it makes them brown nicely without burning.
