I was very excited to see that several silicone items were being made by kitchen-aid, given their product history. I used to work in the food industry and silicone baking mats were indespensible to us. However, this is NOT the same stuff. As the other reviewer said, it produces a rubbery smell when baking (not appetizing, and not like commercial silicone mats) AND my muffins stuck to the pan like glue. If I have to use nonstick spray to prevent sticking, I'll just use my old metal muffin tin.Unfortunately I waited til more than 30 days after I purchased it to give it a try, and now I can't even return it. At least it was cheap when I bought it.If you want some silicone bakeware stick to silpat or matfer baking mats for now. They are great. As for formed bakeware, don't purchase these.I give the product 2 stars because it makes items in a muffin shape but doesn't live up to product claims of non-stick, and beacause of the icky smell it makes.
