Though I've used mine without problems and found it pretty easy to ignite a vasoline-impregnated cotton ball, I continue to have this phobia that the Spark-Lite may fail when I need it the most. I picture the wheel getting stuck, like I've seen on some of my father's OLD corroded Zippos (no offense Zippo users - they might have been Zippo knockoffs).

I really like the Spark-Lite because of its small size and one-handed capability, but the simplicity of other sparkers with essentially no moving parts (Firesteel, Hotspark, Blastmatch, etc ...) seems to make them almost foolproof.

Have any of you had your Spark-Lite fail to work?
