If you're referring to the Kong Gigi, to my knowledge, it doesn't have an easy way to lower if your second falls on the auto-block mode. And you can't belay a leader with it. So it's a specialty device.
Instead of burning them, though, they should drain the oil, and put Karo in the fuel tanks, a la Ed Abbey.
Any guy whose dick is so small he needs a hummer should get a penis implant. Would be cheaper, too!
