I am very pleased with my kit right now, I have Haka 1100mAh eGo battery with some clearomiser that came along, but previously I had a pen-like 510 battery that had a cap with a thread that screwed on it, now I hate that some dirt and tabacco(dont judge me) from my pocket is falling in my mouth piece, So I want some kit that has a case or some protection but not a big one, something I can put in my suits pocket.
