This baking sheet seems to be built to last - it is sturdy, the nonstick coating is quite durable and the tray shows no signs of warping, even at high oven temperatures. The underside of the tray does tend to scratch easily, however I don't think this is really an issue. However, I mainly use this tray for baking bread, and in this instance the double-insulation on the tray hinders the baking process, because the part of the tray in contact with the dough does not get hot enough to facilitate a good rise, and inevitably means you have to flip the loaf upside down to bake the bottom of it. In this respect, I don't think insulated baking trays are the way to go if you wish to bake bread (likewise, avoid using silicone baking mats since they also do not conduct enough heat). I'm not entirely sure what would bake well on this baking sheet, due to the lack of heat it generates on the bottom of the baked good - I guess cookies might work, and it does work fine for roasting vegetables.
