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!!
