Hey banjo, thanks for the post, but I already moded my own e-cig so pretty sure I want to go with a mod. Want something with versatility etc. Like the idea of being able to go 3.7 or higher etc, get more bang for my buck sort a speak. Right now my e-cig runs off of 4 "AA's" and does pretty good. Just looks like I am holding a IED (Improvised Explosive device) LOL Don't want people to freak out on me!!
