Thanks for the plug, dormouse!
As for ValleyGirl, I urge you to give strong consideration to the fat batts. The frequent recharging of your super-mini is going to drive you crazy. The best deal at the moment is Liberty-Flights' 750 mAh Riva-510: $30 (after applying 20% coupon code: ecf) for a two battery/two atomizer kit. Can't be beat. [And, no, I don't work for Liberty-Flights.

I second that piece of advice.
Received mine yesterday after 2 months of using an RN4081 and Vapor4Life's KR808d-1.
I know flavor preference is extremely subjective, but I find that the cooler temperature of vapor from the Riva 510 is far more pleasant than what I consider to be the 'hot and humid' vapor of the VaporKing.
Don't get me wrong, I used the VaporKing and the RN4081 to quit smoking. They were fine and I know lots of folks like the VaporKing KR808d-1 and never move on from that model.
I just enjoy the actual 'feeling' of the Riva 510 in my hand. I have the stainless steel one, and it looks just as nifty as the VaporKing. Best part? I used to take one VaporKing assembled and one extra battery and one extra cartomizer to work with me in the AM to get through the day with no worries. With the Riva 510 I take one assembled unit and a small bottle of extra juice with me.
So, IMHO, VaporKing kr808D-1 has hotter vapor than the Riva 510, and I had to carry more crap with me to make it through the day. Even still, I would refer someone to it if they were looking for a sleek ciggy-esque sized model. Let's face it, Vapor4Life's black batteries with green LED lights at the tip look pretty nifty. I also understand that a lot of folks would prefer the warmer temperature of the VaporKing to something like my RN4081 vaporizer.
But for battery performance, the Riva 510 is rocking my world. I started the battery I am vaping on at 7 AM this morning. It is now 7 PM and the battery shows no signs of slowing down.
TLDR: DaBoom, IMHO, is correct in that you should think about a Riva or something similiar in the future. The VaporKing will do exactly what it's supposed to, just make sure you always take an extra battery and extra cartomizer with you when you're leaving home for more than a couple of hours.
Good luck!
