This cookware is fabulous! I would have rated it a 5-star, but I can't speak to its reliability yet. :-) I first used GreenLife cookware at a condo I recently rented while on vacation. First of all, who cooks on vacation? Well that's what I thought until I cooked one meal in these pans then I was sold. I was amazed at how evenly these pans cooked and how easy the clean up was. The ease of it all inspired me to cook vs us eating out every night while on vacation. I'm sure we saved hundreds of dollars on food that vacation! No matter what type of stove you have these pans provide equitable heat distribution for properly cooked food every time. To extend the life of the pans, follow the manufactures guidelines, (as with any new product), and only use plastic or wooden utensils, use the proper oil and don't heat beyond the suggested temperatures....that's what I'll be doing because I look forward to cooking lots of good food for quite some time in my new GreenLife pans.
