This set surprised me. Based on the reviews, I was expecting to be pleased, but these are way better than I expected. At the time of writing this, I've only had them for about 4 months. They are as good as new. I do put them in the dishwasher, but try to put on top shelf. I haven't had any food stick to them. My only complaint is that the lid handles can get really hot. Now that I know (ouch!), I just use an oven glove to handle them.
