Hey guys, recently i purchase the stv vivi nova tanks.. i bought 2 qty from a vendor. It works like a charm and produces thick cloud of smoke on my vmax, Currently on 2.4ohms. 1 flaws that i noticed is the top cap where u slot in the drip tip, i found it not flushed with the tank body.. mayb a bad batch. its not giving me any problems though but juz being a bit nitpick. Anyone of u guys got a same problem with me?
