The pots and pans are well made and heavy duty. The granite stone non stick surface it thick and feels like metal utensils would not harm it. You can cook in these with or without oil and the food does not stick. The handles to the pan feel a little rough in the hand because they're just one cut piece of metal. I wish it were filled to feel better in the hand. But the handles are well attached. The lids fit each pot completely and have a little steam hole. My rice was still perfectly cooked. 
The baking pans in this set are what makes it amazing. They're heavy duty and have a thicker metal than I'm used to. They could definitely take a beating. 
This set comes with everything a person would need. I expect to have it for a very long time.
