# 239.4 “Lifetime” and similar representations.

If an advertisement uses “lifetime,” “life,” or similar representations to describe the duration of a warranty or guarantee, then the advertisement should disclose, with such clarity and prominence as will be noticed and understood by prospective purchasers, the life to which the representation refers.
