Bests & Worsts Reviews from Amazon

The silicone melted and stuck to my baking sheet. I bought this along with two others and they all did the same thing. This 1/4 sheet left the least amount of residue. I only baked these at 350 for about an hour. I couldn't imagine that I did something so wrong that it melted this silicone mat. The black lettering for the model and origin seems odd too. Two of the mats have crisp clean edges while one is smudged...feels like it's a knockoff or quantity over quality is their new motto. Also, a chunk of the silicone has mysteriously vanished from the orange border exposing the fiberglass. I will be returning all three.
