Query: Not KitchenAid Quality

I got this cooker to replace one that started to burn in one spot. The lid rocked on the crock, and didn't come anywhere close to sealing. Turns out the lid was fine, it's the crock that was warped. I exchanged one for another, and had the very same thing happen. I returned that one also, and went to a local kitchen store where I could check it myself before making the purchase. I had to go with the stainless finish, but at least it seals.
