Bests & Worsts Reviews from Amazon

I used these twice and both times, they came out of the oven smoking, which in turn set my smoke alarm off. Because of the smoke, I would also have concern of chemicals leaching into my food. I gave two stars because despite the above, they are indeed non-stick, wash easily, and fit my baking sheets perfectly. However, due to their reaction in my oven, I have chosen not to continue using them and will switch back to parchment paper.
