I bough two of these for my survival bag and camping gear. One of them doesn't light at all, and the other barely lights, then goes out, but the fuel keeps hissing out of the top. What's the chance that i got TWO duds. I think it's more likely that they just stink. I also read some reviews that say they are great, but they are wrong. Also, since i purchased from Amazon, I can't return them because they contain a hazardous substance...fuel. Do yourself a favor and buy a bic.
