Okay so I'm not that much of a newbie I've been smoking ecigs since about May and I've been here tested that and all, i currently have the buck naked brand battery and the ego-t battery and several tanks, i also use the blu ecig cartridges and I've noticed that refilling my blu cartridges i don't get the strength of a vapor tank, can anyone tell me why? Plus my BNE kit battery wasn't lasting long enough so i bought a backup kit and the juice i got with it is super nasty and disgustingly smooth, and i have no idea how to clean it out so i can put a much better more preferred juice into it
