I have only been using this pan for a few weeks but I am very pleased so far.  I am following the directions closely - not overheating and hand washing (sooo easy) to get the best performance over time.  I have purchased ScanPan in the past but they never last as long as I think they should.  Hopefully GreenPan will become my new nonstick pan company.  I also purchase the Venice Pro saucepan and am very happy with that also.
