Ok, today's my first ever vape......I like it! I got the starter kit that is 3 pieces. Looking at some youvids I see one can use a cartomizer with the 510 batt that comes in the kit, however the mad vapes site I think says it's not recommended. So which is it. I'm asking because it seems to be easier to use and hold more juice. The vids say there is more vap as well, is that true?
