I bought a Kitchen Aid Slow Cooker KSC700 mostly based on the recommendations in the Cook's Illustrated review. Despite some of the experiences from other customers, I ordered one anyway hoping Kitchen Aid had maybe address this problem. My first one cracked on the third time, the second on the first time, all within 20-45 mins of starting. As per the reviews, I was very careful not to put in anything that was too hot/cold. Kitchen Aid was happy to replace the crock liner the first time but the second time they denied this was a problem and rather begrudgingly will send another one. I was surprised at the poor quality of not only their product (we have many of their appliances), but their customer service. I will try the third crock but feel it can't be left alone for long because of the potential fire hazard.
