I had to replace a pan, and it was managed by my retailer Ma Cuisne in Ottawa. Ma Cuisne worked with All-Clad and made my experience reasonable given the stress. I remember taking some time to get All-Clad to acknowledge the failure and they were responsible for replacement.
The replacement pan has been working for years since.
Yes, this retailer - Ma Cuisine - deserves 2 thumbs up.
It is the Teflon peeling away from the edge of the pan. I hate Teflon and try not to use it for various reasons, one being that it wears out way too easily. Based on reviews I was led to believe that All-Clad would be different. Perhaps it is but this didn't live up to the reviews.
I will check with Amazon . . . at least they should be a bit motivated given the amount of business I do with them.
My returns were on teflon too, and my motuvation was similar. So after the returns, I went almost to 'never to no-stick (swiss diamond for fried eggs)' and eventually to absolutely no stick for any reason (poached egggs).
