We bought these just over a year ago as a set of 3 sauce pans.  Specifically bought as it said 'scratch proof', but in 6 months' of use, all 3 pans' coating had chipped from inside, exposing the metal beneath. Took them to the store where we had bought them, they grudgingly exchanged them, saying we've had no complaints, we don't know how you've been using them (hello, we use non metal spoons!). NOW, the exchanged version ALSO developed the chip on the coating on 1 sauce pan, again, we were more than careful with how we stir things in these pans.  Don't understand why the coating is coming off!

Though, if the coating doesn't chip, they're good for cooking, even on very low heat, food cooks nicely.  Only thing is that on our gas hob, the base slides alot, so initially, the pan would slide of when we stir, it was very dangerous, but now we got used to it.
