I've used an old boy for many years as my primary lighter. I've had 2 of them, but gave one to a friend because it's a nice kind of lighter to give away.
The latest one has seen jungles, mountain tops, rivers, oceans, lakes, deserts, dirty bars, and urban centres all without issue. It has been my go to lighter for everything, including pipe smoking, so it has seen some genuine hard use.
The previous one I had saw about the same abuse. Before giving it away, I sent it out to be overhauled and brought back to factory conditions. They replaced almost everything on the lighter (all seals, plus wheel, springs, etc.) and it cost me something in the range of $20.
Not sure about the comments about it being delicate. It has not been my experience, but perhaps I'm just lucky.
It's as solidly built as I could ask for and if you ever did have a problem, they're cheap to maintain. Absolutely recommend it.
