Just wanted to introduce myself. My name is Charles and i am trying the ecig for the second time. I believe my first attempt failed because it was just easier to light up than to worry about batteries but my wife picked my 510 up and has not smoked in two months. I have a riva now and love not having to worry so much about recharging. Like many of yall it has become an obsession as i now have a plano organizer filled with batts, attys, carts and all sorts of flavored ejuice. Been using the 510 and riva with analogs, but smoked my last analog yesterday. I am going all out and dont plan to smoke another analog as long as i live. Happy vaping.
