Not everyone should play with things that go BOOM. The easy part is just don't buy it. Don't whine about the guy selling it.

This product, however has some applications. There are many appliances that fail to function in the bitter cold and high altitude. Butane stoves are in that class of limp wristed products that need to be understood. At -20 deg F, this solution may work fine.

One application involves adding other liquids and gasses to the stoves bottles other than its original intent. The problem always always involves figuring out the plumbing. This guy has helped out with a turnkey product!

Here is some other fodder. Take your empty propane bottle and remove the valve by unscrewing it. Pour some of your fuel of choice into the bottle - gasoline, alcohol, Ronson, etc, etc. Now replace and seal the valve back on. Take it down to your local propane dealer and have the tank topped off. You now have YOUR CUSTOM mixture for your Butane stove.

If you want a custom mixture for your propane weed burner, add styrene packing beads and diesel before you top off the propane tank. The "NAPALM" will stick much better to the brush and grass.
