The cooks essentials cookware we bought (years ago) was wonderful. The presenter always said it was restaurant kitchen quality and I agree. Now I never try and abuse my cookware but sometimes it happens and it held up very well. Over the years two pans were worn beyond belief and while QVC couldn't offer replacements, I was given credit on my account for each piece.
The remaining pieces I still have work fine even to this day and we are talking double digit years of ownership.
