Hi guys, I'm a very happy camper today as I can see that vaping can definitely work for me, I'm not crazy at all about the cartomizer flavor but it doesn't make me gag and therefore I can stay with it until I can get some different prefills or my juice orders come in. I do have one question I couldn't find the answer to anywhere - should I let each battery run dead before recharging? Also, will the batteries be damaged by leaving them on the charger once they are fully charged? Thanks, thanks, thanks, Smokeless Image, my son is so excited for me and I'm excited for myself. I will shortly be posting a glowing review.
