I bought this product years ago. After a couple of uses the non-stick coating started to come off. An on-line retailer that I bought it from replaced the whole cooker but the replacement did the same. After years of sitting on the shelf I called All-Clad before throwing it away and they replaced the aluminum insert, free of charge, with a better non-stick coating. I've used it 6 times since then and now it won't heat. In all the years that I've owned this cooker I've used it less than 20 times. Junk!
