Hi iv been vaping for a few months now and bought myself the subtank mini to go with my sigelei 30w mini box mod. Done everything im suppose to (pre drip the coil etc) but its like vaping poison! Tried both 0.5 and 1.2 coils with different juices and at different wattages but with the same result! Plus the vape is super hot even at 15w with the airflow fully open and i can only take half second hits. Any help will be greatly appreciated, thanks in advance!
