This line of the GreenPan, Valencia Pro, is the best of the best in my humble opinion. Their other lines are OK too - but these are great. I've learned from experience not to use extreme heat (it isn't necessary anyway) and not to use cold water to cool the pan when it's hot. I used to be a great one for running a hot pan under cold water to cool it off quickly. Maybe that wouldn't hurt these pans, but I have read that it isn't good for non-stick pans in general. It's one of the reasons a pan can lose it's non-stickiness so I don't do it. I can't attest to dishwasher results because I hand wash all my pots and pans. My one complaint? More sizes/options please! With lids! Fortunately, I have an older GreenPan (different line) that's the same size and has a lid so I use that with this pan. Their complete collection offers more, but I'd like individual pieces. Anyway, this is a great pan with VERY easy cleanup.
