I have one too. For a cigar or pipe smoker like me, the one I have is pretty useless. I considered it for fire starting in the woods, but it failed "stress testing." Mine (I don't know about yours) is extremely sensitive to any bump that puts one post of the arc out of line, and it fails to arc if there is any debris (even ash) whatsoever in the gap.
For my kits I'll stick to a few Bic's and my Zippo (Zippo, with air tight fuel canister). The Bic's don't like significant elevation or cold. The Zippo burns anything, anywhere, but does not retain fuel over time (thus the canister). But I'm saving my plasma lighter to amaze the kids!
