here's the mystery battery and cartos I have now that I'm better off just drinking the juice considering how crappy the hits are.
I have used those type of clear tube clearos and i can tell you if you keep using them you WILL be drinking the juice whether you intend to or not
but on a real note, there is a metric crap ton of good info in this post, just take it, lots of name brands and product names you can't really go wrong with most of these suggestions. The battery in your picture might not be legit but it is a 510 threaded eGo style battery so it should work just fine it is more about your delivery system. I have some of the same knock offs as you i believe (is the button a BRIGHT "dark blue" and not a white-blue if so then they are probably the same) i say that because the passthrough cap threads have nearly the same texture and machining imperfections, feels like a rusty tricycle wheel when screwing it on. anyways, keep the battery - grab a backup (or two) and a couple 5 buck clearomizers like a T3 or a tank like a Nova and you will be set.
once you spend a little more money and get a little more vested you will justify never buying smokes again because you would then admit to wasting money

and then its on to VV and VW and maybe if your eyes are good and hands are steady a Genesis style RBA
