Based on the positive reviews from some of the guys on this sight, I bought myself a Lotus L11 Gaucho lighter last year. Well, ever since I bought the lighter, I haven't been able to get it to light properly after it ran out of fuel the first time. I refill it and it'll last for a day, maybe two if I'm lucky. I've tried two different kinds of fuel (Lotus and Zippo) and it still will not hold fuel for more than a day or two. Any ideas of what could be wrong?
