All of you need to take a trip over at johnsoncreksmokejuice.com. BEST product on the market. I've been using them for the last 3 years and I haven't touched a cig since.
Anyway, all the questions you have about why your e-cig always floods, short battery life (a full 2 hour that lasts for two days). There's no better e-cig on the market and believe me, I've looked and tried to find a better one ever since Johnson Creek introduced the "V".
Pleased be advised: Not allowing your carts to go dry is the secret to longer life. It also stops the plastic raunch you get once it runs out. So, don't let it run out, and watch how long they last.
No, I'm not a salesman.
