If you are turning your PT upside down and have complaints about liquid dripping out of it and/or getting a lot of liquid in your mouth that leads me to believe you removed the silicone cap off the vent tube on the coil assembly. That is not packing material - it's the seal that maintains a partial vacuum in the tank.
This may be very pertinent. Will test this theory tomorrow and report back.
To all those telling me I may have bought counterfeit products. Everything was bought from ProVape E-Cigarettes: Buy Electronic Cigarettes & Smokeless Cigs - the home of the provari. Unless they're selling counterfeit protanks, that's not an issue.
