I don't want to be a party-pooper but exactly how is this thing better than a good butane lighter, or two? Hard to tell for sure but size seems to be twice that of a mini-Bic.

So how would carrying this be better than having two mini-bic; one ready to go in a pocket and one wrapped in wax paper (good tinder) and sealed in foil to to protect it.

Then there is cost. Mini-Bics go for about a buck a pop. Sparkie, based on a Google shopping search, roughly $12 to $15.

IMHO new products need to be judged against existing, established, products which often have been proven over many years of good service. No need to kill promising new products in the cradle or forsake real improvements. But likewise there is little benefit for a person interested in survival preparedness to place too much emphasis on novelty
