I carry one of these with my camp kit to light fires and heat beads. Already carry the safety butane canisters so to add the torch to the kit was an easy addition. Having said that, these cheapies off eBay can be a but hit and miss. I ended up buying a quality torch head from a hardware store after the first 2 eBay units crapped themselves.

It's astounding, time is fleeting
Madness takes its toll
But listen closely, not for very much longer
