Looks like this might just be another one of those 'hit and run' deal but if not -
1) As mentioned, Ultrex came from hsn, not QVC so of course QVC cannot help you with that junk. I agree to just toss it. That company went out of business, IIRC, and part of the problem was their lack of customer service - along with the fact that they sold inferior products.
2) I have quite a number of pieces from both Technique and Cook's Essentials lines. They have lasted very well over the years, but I take care of them properly and I think that makes a huge difference.
I did have one Cook's Essentials pan (a small saucepan) that started to peel around one of the rivets so I contacted QVC and they could not have been more helpful. They told me where to send the pan and what information to include. Within a week I got a phone call from the warranty people who very politely advised me that that pan was no longer available but offered me two choices of replacement pieces. I ended up with a majorly upgraded pot that I still use today. It also introduced me to the Technique Hard Anodized II line (their best line ever, IMO) and I purchased more pieces in that line. They are all still like new after a number of years.
I've seen so many people here comment that they were taken care of per the warranty, so the remarks that they don't are alarming especially since I had my own excellent experience. I'm not a QVC cheerleader, either. I have complaints about plenty of junky products they sell, but I never found their cookware lines to meet that criteria, nor their customer service.
I think it's just - well, never mind what I think.
