Submited By: David T. on 02/20/2012 There is pretty much enough butane in this for you to do a constant 5 minutes of burning. If you use the max setting for the flame size, it runs out really fast. On the bright side it doesn't explode, but on the down side they don't take propane (you can fill it with propane using a propane adapter for a gun, it will take the propane, but it will just sit in there) | |
