My fry pan from 35 years ago warped and now that I had a new flat glass type stove top it was spinning. I called BelKraft and was upset that they didn’t replace it for free. I thought it was covered under the 50 year warranty but the girl said that warping falls under the “Full Hazard Warranty”. Under this warranty they only replaced it for half price. The new 7-ply pan seems to be twice as thick and so far so good. I suppose I should just be grateful that they’re still around after 35 years.
