Regarding the airflow thing... when I first got the kfl+ I found it a bit too airy, though of course it was completely open; I closed it completely, then gave it one half-turn open, and it stayed that way for about a week-ish. Yesterday I opened it up more, trying to work on the nano problem; it didn't help, but I left it open for awhile; the next time I changed out the
juice, I went ahead and closed it, then gave it the half-turn open, and after just 1 day at the more-open settings, I find that I actually prefer it that way. Go figger!

So I opened it another full turn, as I did yesterday, and yeah, I think I do like it better that way. It's nothing like smoking, and after almost 3 months of no smoking, I'm fine with that. Good riddance to bad rubbish and all that.
