We have been using this liner in our Breville Smart Oven on a daily basis for more than 12 weeks now. I have made roasts, baked pies, and done simple toasting, baked frozen pizzas as well as baked cookies in it. Bake times have been at 350˚ F for an hour or more on some occasions. I have also used the 450˚ F heat setting for at least 25 minutes. I just finished inspecting this liner for "white spots" or other evidence of burns, and I found none. It has handled drips from various foods (sticky or oily) and has simply wiped clean with a dry cloth. There has never been an odor that we could detect, and our small dogs seem fine. I mention the dry cloth and the small dogs for a reason. As far as I can tell, it is probably not wise to use cleaners or submerge this item in water for cleaning. It may trap pockets of water or cleaning solution that can cause the liner to "bubble up" in heat the next time it's used (much like the water inside a popcorn kernel puffs out the kernel when it is heated). The small dogs are mentioned, because teflon produces toxic fumes to small animals. BIRDS ARE ESPECIALLY VULNERABLE TO THESE FUMES. Most experienced bird owners know not to use teflon at high heat temperatures because THEIR BIRDS WILL DIE when exposed to these fumes. I'm not sure about other small animals and small children, but using the "canary in the mine shaft" principle, what is not good for the canary must also be not good for small animals and small children. As for those people who have tried ordering their liner "a little big" and cutting it down to size, this may actually also damage the liner by exposing the inner fiberglass lining by "rough" scissor edges creating fiberglass dust. As a basic rule, most drippings are going to fall where the food is located, most food will not touch the sides of the oven. Big "boil overs" are going to smoke and be a big mess no matter what. Avoid having to cut the liner by measuring and then ordering the right size to begin with. If the heating elements are too close to the liner, fire is possible. This seems logical. It is also possible to set aluminum foil on fire, and those fumes are toxic as well. Anything that burns will produce smoke, and nothing in that smoke is safe to breathe. If aluminum foil has been working fine in your toaster oven, and the manufacturer says it is an acceptable liner, then continue to use that. Breville warns that aluminum foil in their smart oven is a safety hazard, so we don't use foil. So far, so good with our liner. I will continue to use caution and inspect this item on a regular basis for signs of wear and tear (or burning as our case might be). The bottom of our oven has stayed clean and free of burn marks from this liner. Anything on the bottom of the oven that burns or catches fire is going to leave a mark. The general rule here would be: don't leave your home unattended while a toaster oven is in use. If you smell smoke, turn it off immediately, and inspect the liner for fire damage. Be aware that ANY teflon product used with heat can be toxic to birds, and possibly toxic to small animals and small children. So far, so good, but be careful!
