I picked up a spark-lite recently, and was able to get tinder quik burning with it. It took a lot of fluffing, and a lot of tries. I'd hate to try it if the tinder quik started out wet - I doubt I could get the fire going at all in with a spark-lite in that case.

I may just go with a ferrocerium rod instead, it gives me much better sparks. I can't start a fire one-handed with it, but I usually can't with the spark-lite either!
