>>1486150I used to buy lighters in packs when I was tobacco fag, so I always have a lighter, so I had like 20 when I quit 4 years ago. Since then I use those lighters occasionally to light up a candle or camp stove or something and they never, I repeat - NEVER fail. They still hold some gas and work fine after 4 years.
The bottom line is: it doesn't fucking matter what lighter you have for emergencies. It will most likely work anyways.
