I had concerns about non-stick in a slow cooker because of the prolonged heat, but with low heat and non-acidic ingredients thought it would be ok. It's not. The coating is bubbling and flaking even with low heat use. The ease of cleanup is great, but it's not worth it at this price and with the health risk. Even with the warranty, I'd gladly purchase a ceramic insert replacement at the equivalent of All-Clad's cost to fix the problem but haven't seen them available anywhere.
