I have the 3 qt pot that I purchased in the late 1970s.  The bottom of the pot warped and made it impossible to cook on a glasstop stove.  When I contacted the Farberware customer services dept about the warranty, they stated that although it DID have a lifetime warranty, they would not honor the warranty because the original company had gone out of business and the Meyer Corporation acquired the license to mfgr the Farberward cookware and voided the warranty.  So, lifetime is not lifetime!
