I don’t know what happened to this pan but after about 3 uses it started to develop discoloured spots. Then the next time i bothered to notice, they had become about a dozen small holes right through. You hold it up to the window and the light streams straight through. I’m currently lining it with alfoil or baking paper, so it still works, kind of. But what a disappointment. I’d return it, but I can’t say i’m 100% sure it wasn’t something i did. I don’t purposely mistreat my cookware, but i don’t baby it either. I expect it to be up to what’s expected of it 🤷🏼♀️. I certainly wouldn’t buy another one.
