I just purchased a new Kanger Aero tank from my local vape shop. I followed the few step directions to put it together and fill it then waited for a few minutes to allow coil saturation like stated. The first hit I took I got nothing but a mouthfull of e-juice. Took it apart and restarted the process. This time it seamed ok but the air control was so tight I couldn't get any draw. So I try and adjust the draw and all the e-juice leaked out. Does anyone have any idea what I might be doing wrong?
