Reviewed by Alex Hocking - 14th May, 2020 Utterly useless I pop something like this in my walking pack as an emergency back up bit of kit. Survival kit is carried as an insurance policy - if all else fails you fall back on your simple survival kit. I tested this as I do all my survival kit and it failed miserably. I got two or three sparks off the rod before it stopped producing any sparks at all. In the process the rods themselves came free from the housing. Do not rely on this - don't even buy it it is worse than useless.
