This is a solid non stick fry pan which I chose for use on an induction cooktop. We use the pan about 2 times a week and after a couple of years the non stick surface is starting to darken, although it still works  well.   An absolute requirement of using this pan is to never ever ever go above medium on the heat level. To do so means you will char the no stick surface, it will darken, and you will not be able to clean it. With an induction cooktop this is very easy to control (I just never ever set the dial above 6/9). However this requires patience on a standard cooktop and my daughter (with husband and kid) uses it on a standard cooktop and the pan is garbage after a year because she has neither patience nor induction. If it was only my experience, I would give it 5.  My daughter complains about the same pan so I gave it 4.
