Well, I'll tell ya, I purchased a while back a two burner propane lighter (The Xikar Enigma) from The Tinder Box. One of the selling points, besides the lifetime warrenty, was that if it ever went bad, rather than sending it in, I just have to take it to The Tinderbox and they will trade it out for a brand new one off the shelf. The Xikar's are the only ones they can do that with, as the Colibre company and others that have a lifetime warrenty still require The Tinder Box to send it in to them first.
As a sidenote, I haven't had a problem with my lighter yet.
