Amazon has a couple dozen brands that are about identical and with the Explorer name on them. They're different brands and prices but I suspect that they all come from the same Chinese factory. They have 2 different types of burners as seen in these photos. One has the spark on top and the other has it down inside. I don't know if one is better than the other. Has anyone compared them? Just from looking at the photos, it looks like the top spark type would be easier to get in the tinder.
