[quote name='louiedog']How did the flint fall out? There's no room at the top for it to come out. Did you unscrew the bottom and something happened to it? It sounds like you were playing with it and lost an extremely cheap and easy to replace piece.[/QUOTE]
Yeah, never heard of the flint falling out. I've had some get jammed, either the top getting snapped off, it ending up cocked a bit sideways or the flint wearing itself at an angle at the top. Nothing major.
Also, I haven't really messed with the one I got, but some of these are sort of cheaply made. Almost always, though, it's the casing and not the actual lighter itself. My friend used to regularly buy them for $5 and have the lids break off. I have over a dozen "Zippoffs" and three Zippos. I tend to just get the free ones when I can so I don't have to buy flints.
