I was thoroughly underwhelmed by the Solo I had, and it didn't long survive in my equipment inventory. Bic lighters are considerably cheaper, and vastly more reliable IMO. As long as I can see fuel in a Bic - or even cheaper knockoff - (assuming you buy the transparent kind, which I highly recommend) it will light. I've never had a failure yet. Another plus is the fact that they'll still generate sparks long after the fuel is exhausted, something that can't be said of the finicky electronic ignitions on the Solo-type lighters. Where fire-making equipment is concerned, simpler is definitely better, and I test, test, test all my fire making equipment before I commit any of to possible field use.

This is why I'm also a big believer in Vaseline soaked cotton balls, as they seem to go up easier than anything else I've tested - short of maybe gasoline soaked rags...which probably wouldn't be amenable to carriage in a PSK! Most of the commercial tender seems to ignite pretty easily too, so long as you fluff it up good before using it.
