I have been using my set for a year and a half, and because of how the bottom is designed my pans are essentially getting ruined with each use. These were a wedding gift and I'll probably need to have them replaced within a year. They have only ever been hand washed as my dishwasher is not large enough for pots and pans. And in your care instructions it doesn't say if they can't be used on certain stove tops. Essentially these seem like they're only able to be used on a flat top electric stove, which not everyone has. I was so excited when I got these. Rachel Ray is one of the brands I enjoy because you have the colors I want in my kitchen, but I am very disappointed in the quality of these pans and that I will need to have them replaced already. They should've been good for at least 5 years of use.
