I'm not very experienced with ecigs; I've been using one mod and one brand of 510 carto since I started vaping. I'm looking to expand into other ecigs and other ecig mods and am considering the 510 starter kit on AVE. I'm thinking of picking up one for my mother and one for me. I have a question though, do these only use the cartridges and atomizers, or I can pop a 510 carto on it as well? What exactly is a cartridge for? Don't you drip into the atto?
