I'll have to throw my agreement on the 402 battery seemingly performing better than the 401. Plus I like the shorter design, despite less battery charge than the 401. I'd love to see the 402's able to be ordered on the site by themselves, plus a case to accommodate the 402's and not just the 401's.
I've had my Pilot, my first e-cig, for a week now. I would say that it's probably taken me until now to really grasp the best way to get the most from it, and yes that includes the long, slow draw without much force. Although I have to say that even in its best form, I don't get a "ton" of vapor, I get moderate vapor that roughly equals the output of my analogs of choice, Camel Crush. Though I am considering reading up on how to cut the liquid I have with glycerine to increase the vapor production.
