I’ve had issues with every butane lighter I’ve had. Given they’ve all been on the cheaper end, seems strange that they’ve all died out on me. My most reliable one is a zippo insert that fits in the standard zippo lighter case. But now that one’s been acting up too. Is there some maintenance that I’m supposed to be doing on them? Are the more expensive ones worth investing in? Or will they also crap out on me after a while?
