@MsAnnThropy That's what it almost always means and when it doesn't mean that, it means "we have a legal department absolutely lousy with attorneys, and you don't."
I bought a Waltham watch once. Back when Waltham was one of the best names in watches. $240+ for the watch. It had a Limited lifetime Warranty. It quit in less than 2 months with no abuse. When I took it back they told me the Lifetime was Limited.......and that watch had evidently reached it's lifetime. No shit...that's what I was told.
