Personally have no interest in the product (not a smoker), but I am curious about a few things:

1. how long does a refill last? how do you quantify it? in # of normal cigarettes? minutes? 2. time between battery charges? 3. does the second-hand vapour smell similar to the flavour names?

Also, there's some kind of disconnect between your "how it all started", the name of your product, your front-page advertising (ok, the pretty girls), and the scary bottom-of-page warnings. I think you need to make your messaging a little bit more congruent.
