no bud im using red bull, was vaping nicely for a week now til i changed coils lol, on the nova it still wont vape it taste mega burnt, i was using hangsen tobaccoo liquid and that was burning non stop from day 1 on evod and nova, i switched to redbull and had no problem at all until now lol, only thing i can think of is maybe i dry burned it wrong as i wet the coil itself then dry burn... i notice alot of ppl dont actually wet the the coil wire but iv been doing it that way all the time with the redbull and was all good. now i put a new coil in its just gone wrong lol
