The performance of the product I love! The pot gets chipped at the lid edge. I have the third lid coming, and the warranty handles the issue effortlessly, however I am afraid without design change I don't know how this issue won't occur again. I had purchased the newer model for my daughter as part of her Christmas gift, and I noticed the pot on that has a recess where the lid meets the pot itself, this would stop the non-stick surface from chopping. I was a bit disappointed to hear that since I purchased this unit at a department store vs the Ninja, we site my warranty isn't as complete as I i purchased at a store. It seems if I purchased on teh web site I would be eligible for a replacement of the unit itself, but since purchased at a store, They will replace only the defective part, which by design will probably happen again.
