Query: yet another cracked insert

I've used it many times with no problems over a few years. Then I was clumsy and broke the original insert while washing it. The replacement KitchenAid crock arrived a week ago. This insert has NOT been banged around and it has NOT been exposed to extreme temperature swings. That means I waited until it was at room temp before washing it for use and did not place frozen food in it. It was not filled with food, placed into the fridge, then put into the cooker base. Even though it was handled with much care, it cracked within 15 minutes of being used for the first time. Until today, I would have only said good things about the cooker. Obviously I cannot recommend it now. I don't know why I had no issues with the first insert, but the replacement one broke immediately. Not worth the money for sure.
