I love the way it says 'Made in Occupied Japan', even on the warmer.
The guy thinks the Chinese ones are copies of the Zippo? D'Oh. Zippos are a copy of the Peacock. He doesn't even test the original....
Two tips for using them:
The instructions should say to heat the element with the underside of a match. That's correct. No direct flame required. The element needs heating up, not soot from an open flame. Match. Not lighter.
Secondly, Compare the size of the funnel with the size of the warmer. It's probably half the size of the warmer. That means the warmer holds two funnels worth of lighter fluid, not just the one and will then last all day.
