thanks to all for the info. I recently bought a zippo to trial-replace my EDC bic (I don't smoke) for the following reasons:
I like the "refill" aspect, more enviro friendly
I like the American Made component, and it's long history
I like that it is very wind resistant
I like that the cover can be partially closed over the flame to quickly warm up the unit and function as a quick handwarmer.
I like that it's shiny mirror like finish makes a decent little signal device
I like that you can fire it up and set it down under a firelay and it will continue to burn as long as you've got fuel.
I like that it's a neat little gadget and very cool
I like the guarantee for free repair by zippo, and the replacability of working parts.
I DIDN'T LIKE NOT KNOWWING HOW OFTEN TO REFILL IT, BUT NOW I DO, SO THANKS!!
