I am obsessed! I recently was using green pans, and was very frustrated with how scratched they were after only a year of use. The ninja pans literally check every box; they are scratch resistant, dishwasher, safe, metal utensil safe, nonstick, chemical free and they come with a 10 year warranty!! I have cooked for several weeks using these pans and I can attest to their quality quality. You do need to let these pants heat up properly but once you do nothing sticks to them and everything cooks perfectly. I also love that they stack! I have limited cabinet space and these no matter what order you put them in stack fabulously, and so do their lids. I cannot encourage you to get these pots and pans enough as they will be the last ones you buy for a very, very long time.
