Just bought a KGo to battle cigarette beast. 
Dark City Vapors samplers  
 
Ive found the favors left a bit to be desired ... And still trying to get used to the fact that there is no substitute for the burning flavor of a real cig.  
So far, Im a bit turn off by the tobacco juices I've tried (DarkCityVapors: Dk mnt blend, mountain 55) . 
Mnt 55, is a little closer to what Im liking , that is not too sweet. 
 
I actually quite dig the StrawberryMint, but found the vapor a bit weak ... 
 Blueberry freeze,  jury's out, but right now, it's leaning toward a thumbs down. There's a creamy note that's not to my palette.  
 
So, while its a little frustrating to be only MOSTLY satisfied flavorwise, I love not being a "smoker" .
