A zippo requires some maintenance and upkeep in order to work properly. A mechanical clock will not work if you don't wind it. Doesn't mean it's a bad clock.
Smokers never have issues with their zippo b/c they use them and fill them daily. I would look at a butane cigar torch lighter by Colibri or Xikar.
Alternatively, google "creme brulee torch" or "kitchen torch"
Yup, ^^^ that.
I have found that a Zippo pipe lighter works better for lighting a fire, than a regular zippo, if you need to hold it horizontally to do so. My Zippos work first time, every time.
