After a friend convinced me to quit smoking and try out vaping, (Hes been doing it for a couple months now) I looked into custom mods for a couple weeks to find the right one. I came across the rough stack and being in the Army I needed something small, long lasting and durable. After having the rough stack for 7 days now I have to say that it was everything I was looking for and more. If I was to ever lose my rough stack I would not look anywhere else, I would order another one without thinking about it. It is just plain and simple a wonderful mod. Thank you MadVapes for ending my 15 years of smoking (7 days now without one single urge to light up).
