Smokeless Image just came out with a T3. It requires use of their X2 battery. I'm not familiar with the G6 so I don't know if it would work.
kanger makes 808 clearos
KR808D-1 blank clearomizers - package of 5
I haven't heard good things about V4L's cartomizers.
I use chibi tanks from Parkes...... just a plastic tube with grommets and o-rings... if I want to use them with my 808 batteries I just put an 808 carto in them..... have tried clearos and vivi novas with OK success but seem to keep coming back to the punched cartos in the tank.....
Which one of these works with a standard volt carto, if any? Or all of them so long as they are the right width.
