I wouldn't really bother with this product. As Eddie Stone has indicated this form of fire lighting is purely for an extreme survival emergency when no other forms of firelighting are available.

I would put it in the same category as the wire wool and 9V PP3 battery firelighting SERE tacticool fire lighting trickery. A cheap Chinese made $3 Butane Windproof Lighter from DX is a much more sensible proposition.
