I’ve had this slow cooker for years. I loved it and was sooo happy when I got it. It works well and looks nice. Unfortunately the lining on the insert started to bubble and I contacted All-Clad and they replaced the liner. I was happy again. But the lining on my replacement is bubbling now too. I’m so disappointed. I don’t want to throw it away but I can’t use it so it now sits on a shelf in my garage hoping All-Clad will just make a ceramic liner that fits this model.
