I would recommend this little guy, mine is still going strong over a month and still lights without adding fuel. It's worth every penny for this little guy. Take a small heart medicine capsule at cvs and put extra lighter fluid in it and your set. I have backups of course both flint, magnesium and a zippo as backups. But this hasn't failed yet and has been the best for the buck. I still haven't found a reliable place to get one cheaper yet but I have 3 of them. One on my edc, 2 in my bob. Do a search for airtight flint on e-bay and I'm telling you, you'll love this thing. It's awsome, I just wish I could find a place cheaper.
