A) NEVER been a smoker
That said, I like backpacking/camping.
Bought a UST Trekker stormproof lighter ~12+ years ago. It's been the most reliable lighter I've ever used. Only ever been filled with Vector Quintuple filtered butane (again, I don't smoke, so I still have the same 12+ year old can of Vector butane).
It still lights first time, EVERY time (simple trick is to press the button a little slower, so I hear the hiss of butane before the click of the piezoelectric spark).
I've left the thing partially filled, with my gear unused for over a year (didn't have the chance to go backpacking). Yep, still lit up on the first try.
It WAS bright orange, and is now kinda grimy, but just tested it again, and still lights on the first click. I use it as primary ignition for backpacking, but also carry the UST BlastMatch for a backup. Tough SOB with the rubber armor and cap. It's been dropped on rocks, and the rubber armor shrugs it off.
As with any butane lighter, doesn't work well at high altitudes. For Winter camping, I just keep it in my jacket pocket so it stays warmer than the ambient temperature.
