Query: Lacks Quality

Sure, it was nicer and newer than my old Rival slow-cooker... took a bit longer to cook things, but loved the 'keep warm' setting. THEN, stoneware base totally separated from rest of insert while cooking chili overnight.(Broke into 2 pieces). Awoke to dried-out contents in pot, and liquid all down cabinets, floor,under counter appliances... a huge mess! Product had been used less than 20 times. Customer service response was "Sorry....product out of warranty" I want my old Rival back!
