I had a couple of Colibris go out on me. One of them within the first month I had it. I don't recall which models they were, but I think they set me back $60 and $100. I next tried a few cheapie torches that worked well for a bit, then also took a dump.
Now I exlusively use soft flames. I like them so much better than torches. My #1 lighter, coincidentally, is a Colibri. The CEO Elite. It's got a giant resevoir and a fuel capacity window. I've beaten that poor lighter to death in the past two years and it's still going strong. All I do is pop in a new flint every so often, and those last a long time as well.
I also have a Prometheus Barron and ST Dupont Ligne 2. They are both flint/soft flames as well.
