two weeks after a bunch of us decided to start e ciggin, we have a bunch of dead batteries, burnt out atomisers, we all bought n joy kits, blah, etc. blah. modified one of our battery solderin' irons to power the last working atomiser we had, then ran outta e juice. anywaywe know a little better now. with nothin else to do we took one of our penlights and modified it for e smokin. it has two interchangeable, push on and pull off atomiser leads. one for 901s and the other for classics, rear push button manual switch, the batteries are aaaa 1.5s and they last about 60 to 80 good puffs, depending, but that is with smoking the edible massage lotion, now we aint even got that. ordered some supplies from puresmoker. and until that comes ,we been lookin for options to put in there to fire her up, catch y'all later..
