I like the sizes and actually trust their products over china made big box store ones. I did have one make a noise (snap/pop) on its third time in the oven but no warping occurred. The nonstick is very impressive and yet haven't had anything stick that I have had other non stick pans stick to. They do sound and feel a bit thin so I will baby them a bit to get the most out of them. I would still recommend these over any cheap box store or budget twin pack pan in this price range.
