I have been vaping for a couple of weeks now with my 510. I ordeered my wife a 510 last week also got some extra batteries and extra juice so i wouldn't run out. Guess what my post office lost the package and I only have enough juice to run me until Xmas day. Needless to say I am ....... The only reasponse I got from my post office is that they remember scanning the package and put in the bi for delivery but can't seem to locate it or even know what it was delivered to. I don't want to go back to analogs any ideas for juice?
