Has anyone used the warranty? Our large skillet warped.

No I have not used the warranty, but can you tell me how you keep these clear, everything sticks to them and it is very difficult to clean. I would contact Amazon in reference to the warranty.

Do these work on glass top electric stoves?

Are you ssking about a regular glass cooktop, or an induction glass cooktop? Either way, the answer is yes. Any pan will work on a glass/ceramic cooktop, but you nerd ferrous (magnetic) cookware for induction, and these pans work incredibly well, with even heat throughout the whole pan. Highly recommend.
