Lately I've been getting frustrated with my vaping experience. I'm currently using a carto tank setup on a segeli (sp?) zmax. I have a china gg as well, but the button module (which I have replaced about 5 times) has never worked correctly. Anyhow, I am going through about a carto a week and want something a little more sustainable. Maybe a rebuildable tank on a decent but cheap mechanical mod. I have never used a RBA before and want to get into it because it seems easier to just keep a bunch of wick and coil and i would never have to worry about running out of cartos. If someone can show me to a crash course in RBA's that would be great too, and also any siggestions would be appreciated. I am in Afghanistan and bandwidth sucks. (this is also why it is getting hard to keep supplies on hand) HELP ME PLEASE!
