OP... zippos honestly suck. My biggest problem is that they run out of juice within 1-2 weeks of filling. The only thing that's nice about them, is if you are in a 'survival' situation, you have a spark with a flint and wheel (which you can get out of a bic, clipper, any wheel lighter really).
They're a very cool novelty, and some people absolutely love them! But realistically, if I have a lighter, I want to shove it in a bag, pocket, car, etc. and have it work every time. I don't smoke, so I don't depend on lighters all the time, and I don't want to spend any time constantly maintaining, or in my case, spending money on lighter fluid that will just go 'up in smoke'.
I saw a deal at a store, buy 5 for the price of 3, and just shoved them everywhere. I have 2 in my EDC bag, two in my car, and one home. In the rare case I need them, I use them, put them back, and repeat.
