I am very disappointed with my slow cooker, but even more horrified with the All Clad company. The coating on my aluminum insert has started to bubble and peel. I bought this appliance over a cheaper brand because it was All Clad. This defect is a health hazard and the company should be very concerned.  After reading the reviews, I find I am not the only person who has had this problem. All Clad should try to correct this defect, especially if they are a reliable company, a company that stands by their products.
