I’ve only been using my GreenPan Rio ceramic skillets for about 2 weeks. So far so good. They heat quickly & evenly, are lightweight & I love the ergonomic handles. I am using these skillets on a gas stove but keeping the heat low, per the instructions on the packaging. I am also using olive oil when I cook in these skillets (again, per the instructions which say that spray oils, which I usually use, will burn onto the nonstick surfaces). These skillets are oven-safe up to 350 but I have not used them in that way yet. I handwash the skillets with warm soapy water & so far the nonstick surfaces have held up. I enjoy using these skillets & hope they will last for a long time.
