I was given a Kitchen Aid slow cooker for Christmas. Sometime after the third time I used it, I noticed debris inside the cooker when I removed the liner. Examination revealed tiny cracks in the ceramic liner. The next few times I used the cooker, the number and size of the cracks increased. Kitchen Aid agreed to replace this with their "Hassle-Free" return policy - However, they continue to tell me that their supply of this cooker is low, even though it is available on their website for purchase. I have been waiting since February for this return to happen. They just keep saying there are supply problems as they get replacement cookers from a different area than the new ones (I find this hard to believe). They have now given me a new date of May 14th. Is anyone else having this same type of problem?
