Got the Istick 30w through the door about a week ago and a nautilus mini tank, loving life. Reading other forums though it seems people are adjusting volts and wattage a lot more freely than it seems possible with the istick as when you adjust one setting the other adjust itself accordingly. Is that meant to be the case or is there a way to adjust one without the other? Also what voltage should I be vaping a 1.8ohm bvc? Cheers
