I used to smoke a fair bit, I had various Zippos. After a while the lid hinges would fail and the lid would fall off. I repaired them myself but I had a really nice Brass one that I liked. Zippos apparently have a lifetime guarantee. I often wondered if they would repair them for nowt I sent a few emails and never got an answer. In the end I just mailed it to the Zippo agent in Singapore. I forgot about it. 4 or 5 months later a package arrived from Pennsylvania, inside a shiny looking repaired zippo. The case had been repaired and the insert had been renewed. Can't get any better than that for after sales service, I was quite impressed. All for no cost.
