I just received my order of fire plug, spark rod and travel tin and tested one of the plugs to see just how good they are,... after striking the spark rod twice, I had a fire that lasted over 4 1/2 minutes,... as a result, I just replaced my fire making stuff in my EDC pack,... If I ever NEED a fire, I now know that this will provide,... Thank You Bigfoot Bushcraft for your GREAT product.
