Ok  let me start out saying this is a set of heavy duty cookware.!  They aren’t your flimsy set of cookware you get at some stores. They cook great and no problem with them sticking so far. I love how everything stacks inside itself. The way the handle is made it lays across the pot of the bigger one. The handles are solid with no screws in them like some that will always work lose over time. I haven’t used them in the oven yet but I usually only use baking dishes and pans. But I am really happy I got these. This will be my go to brand from now on. Great product
