I love this FireLite Mini. It's the only thing that I 100% trust to start a fire.
With a mini Bic you can run out of gas, be at too high of an altitude, get it wet or get it oily. Matches can fail or run out. I also have the Spark-lite sparker and it works well but it also fails if it's wet or oily (I've used it). I'd had it let me down once when I accidentially used it with slightly oily hands which then got on the flint and stopped it from sparking.
The FireLite Mini always works. You dunk it in oil or water and get it sparking again in just a few strokes. Sometimes I carry a mini Bic too because it's a bit easier to use, but I always carry the FireLite Mini because it's the only thing I totally trust.
This is a great piece of kit for 0.5oz. Mine is actually a bit lighter because I replaced the cord with lighter stuff and saved a gram.
