I loved the slow cooker... until the ceramic insert cracked! I was hearing little popping noises and didn't know what it was. Then I realized that the the insert had cracks! All Clad wanted the original receipt to replace it, so we took it back to bed bath and beyond and they exchanged it. The second time we just out right returned it. The cracks all happened within 3 months of use with no extreme temperature change William sonomas is recommending that we try the more expensive one with the heat-responsive cast-aluminum insert that functions as a cookware in itself (can go on the stove top)
