just got my starter kit in the mail, the cartridges in the starter kit came empty, and i got a bottle of smoke juice with it, but i'm not sure how to fill it? i got them from electronic-cigz.com, its an m401v2...i'm a noob, so i'm not sure all the info you would need. i literally came across the package like an hour agao, so my battery is on the charger as we speak, i've been looking all over, but cant find anything helpful telling me how to fill it up...
