Consumer reports does a non-stick pan test where they fry an egg without oil repeatedly until it starts to stick. The point is that normal use degrades non stick surfaces, so every non-stick pan, no matter how fancy, will one day be garbage.
Don't get me wrong, I use both non-stick and metal surface pans. I think they both have their place, but I think of non-stick pans as expendable.
The bees know and they're into it.
