I'm so/so on the set. I try to follow the directions and limit the amount of oil and I don't use non-stick spray, but just about everything sticks. Also within the first 2 weeks, one of pots already has a chip out of the rim.
This is the best cookware I have ever owned! Stylish, well-built and very very easy to clean. Nothing will stick to it. Make sure to use plastic utensils though. And if you can hang them rather than stack them I recommend.
