Well, i recently got a vamo APV, and its doing great so far. however, despite finding my dream APV im still in a manhunt for my dream tank/atomizer. i purchased 5 vivi novas with my vamo but now im down to the last one from the center post bending off of the side enough to let juice into the mouthpiece. Carto tanks slip out and have made huge nicotine messes in my pocket, and most clearomizers share the same concept as the vivi nova and suffer from the center tube getting bent. Im a fairly active guy, hiking, all sorts of activities and also work in a shop so my equipment does take some wear but nothing extraordinary. Does anybody know of a highly durable tank?
