After having for about 1-2 years max the liner started to bubble and peel.  All clad will not replace it.  The insert costs almost as much to replace as the entire slow cooker cost.  I did replace it because I love how the slow cooker looks and functions.  It is a shame that the company cannot fix this problem.  I will say that my replacement lasted a little longer but now here I am again with the same problem.  Very expensive to continue to replace this product.
