There are a few different tanks out there MAP tank, J Tank, Lava tank etc..... the carto is inside the tank and it has a couple of holes in it so the juice in the tank gets into the carto.
I believe you can only get V2 ecigs from V2. There are a lot of coupon codes out there if you Google it. It is a KR808D-1 and can be found cheaper at other places.
If I read your post correctly you got 7 hours out of your batt today. Thats pretty typical of a 650 mah eGo batt. LR attys do drain batts quicker than reg attys.
Interesting. I havent heard of this happening, but since the bleeding stopped and you continue to vape, I believe it had more to do with stopping smoking....... just a theory.
I am satisfied with my eGo. I use it everyday. That being said I enjoy buying various mods. Not out of the need to find a satisfying mod, but rather out of my enjoyment of trying new devices.
Glad to hear you decided to give vaping a try again.
