I bought a Kanger ProTank today. I fill it up with juice, waited a couple hours to ensure it was saturated and I began to vape. I can get about 2-3 drags on it then the next vape burns. I turned it down to 4.0 volts and I still have this issue. I'm using a 80/20 PG/VG blend. It came with two heads. I even took one of the spare whicks out on one of the heads to ensure the lower whicks could get more saturated and I still have the same issues...
