I had previously had the Caphalon oil infused non stick pan set.  Every pan after about 1 month would stick even with oil  Yes I have cooked with no issues in stainless steel so it was the pans.  No I did not want a replacement set as offered.  I decided to purchase the ninja NeverStick pan set and loved them and no nothing sticks.  I decided to add the 4 qt pan because I needed something a little larger.  I love it and the set of pans.  I highly recommend the Nnja Foodi NeverStick pans to everyone looking for a solid made set of pans.  By the way they can go from the stove top to the over to finish cooking, no need to transfer to an oven safe pan or casserole.
