Windmill=crapMost petrol lighters leak or evaporate to quickly. Z plus or thunderbird insert is the way to go. I have the flint/butane insert. IMO the best choice as no piezo to go bad.
I thought I'd replied to this thread already obviously not Anyhoooo .... I've never owned a jetflame lighter that's worked properly by the time its reached its third filling. I don't know why, but they just don't seem to burn like they do when they've new. I have a few zippos ... don't use them often though. I have a couple of IMCOs which see a lot more use than the zippos, but they're still not my "regular" lighter. For me you just can't beat a Clipper lighter (regular or mini) as they hold fuel longer than the others, they're reliable and dead easy to fill and change the flints, and of course they're cheap. I do like using my IMCOs, but I'll always keep going back to my Clippers for cheap, simple, hassle free reliability. Also, if you drop a Clipper lighter whilst using it, the flame goes out - not so with a petrol lighter! I don't climb mountains so altitude isn't a problem - and even in the strongest winds, I can still always find a way of lighting a cigarette with a Clipper
