I got my 510 today from Cignot (who was very nice!). I plugged in my USB PT, then blew out the atty really well onto a paper towel while that charged for a bit. I gave it about 20 mins. Screwed it on semi tight, which is what I read here. Put a couple drops on the atty and used the mouthpiece that came on it. Not too much of that bad taste I read about, but I was not too fond of the flavor (tobacco). So I put on one of the carts that came with it and let it set a minute to wick a bit. Did about 5-6 puffs until some good vapor came out, then let the atty cool a little. Then I started doing a few slow drags into the mouth before inhale. Good lord there was some throat kick, even without too much vapor. Seems like a shorter drag hits the top of the throat, while a longer drag hits down near the base of the neck. I also have found that even with the manual battery, a quick puff then drag gets a lot more vapor. I'm interested to see how this does after a day or two of break in! 
I'm not so hot on the tobacco or marl flavors so far, but may be the new atty. Think I'll try out a watermelon or something.
