Review on Japanese-made Replacement Burner for Standard Size Baby Peacock Hand Warmer by David Reyes

This warmer is good for warming up your hands when put in a woolen jacket pocket. Haven't used it with other jackets yet. I find that the fuel gauge cap that comes with the pocket heater helps ensure it isn't over filled or if it only needs half the burn time etc, it's also very easy to light and will burn until the fuel is gone is. I've ordered an extra large for really cold days at work but haven't received one yet. If it's as good as the smaller version, I'm sure I'll love it too!
