First customer update:

All in all, I like it.

It's not a 100% substitute for cigs, and it doesn't kill the cravings.  I ended up smoking 3 actual cigs yesterday and will probably do about the same today (I'm normally a 10-12/day smoker), and I'm still a bit shaky from lack of smoking.

Anecdotally, I'd say 1ml of fluid is ~= 2 cigs.  Maybe 3.  But there's a psychological component that this just doesn't match.

Also, my lips are chapped to the point of bleeding, so invest in some chapstik or blistex or something.

This is all product issues, though, I'll still say farlack kicked the ass of all expectations for delivering the product at a good price in a timely fashion.
