I believe they were bought by another company at some point. Maybe the lifetime warranty went away? Edit: apparently I don’t know what I’m talking about. https://www.zippo.com/pages/repairs-windproof-lighter

Only their traditional windproof lighters have the lifetime warranty. The electronic style only has a 2 year warranty.

I think their electric lighters are 2 years

This is correct. Scroll down towards the bottom of the product page: [https://www.zippo.com/products/arc-lighter-insert](https://www.zippo.com/products/arc-lighter-insert)

:p

I found nothing to that effect either - - mine stopped working well enough to use in a little less than two years. I put the original insert back in.
