Review on SOMGEM Permanent Match Keychain 2 Pack, Kerosene Refillable Fire Starter For Outdoor Camping Emergency Survival - Waterproof Flint by Kevin Mills

This thing is a novelty item, it's not actually useful. It's extremely heavy for what it is for starters. Secondly, once you light the match, the flame ends up being 4+ inches and burns off the very limited amount of fuel in the wick within 5 seconds and burns out the wick. it's also impossible to fill without overflowing it.It just can't regulate the burn rate to last. If they could fix that and give you a longer lasting .5" flame, it would be very cool.
