I just got my Boge Rev 2.1 and the draw is so damned stiff on it. I seriously hope there is something I can do to help with the super stiff draw. The same cartomizers on my Ego batteries are amazing, huge vapor clouds with tons of flavor but on the v2.1 there is little vapor and flavor. I have found that if I slightly unscrew the cartomizer on it, it improves the draw a little bit but it also wiggles around alot. Does anyone know how to fix the draw?
