I have had nothing but problems with piezoelectric stoves, lighters, you name it. They have the maddening habit of not working right when things HAVE to work. Bics seem to be bombproof.

It was nice to read that others have had good experience with their peanut lighters, but I'm ready to ditch mine from my EDC and get a BIC holder instead. It has failed several times on me in the winter. Luckily, I always have other means.
