Ive had an ongoing issue with the kangertech protank 2 now for several weeks. First off, this issue has nothing to do with the device itself. I screwed in a very old, eGo-T Joyetech and it vapes perfectly fine. So the issue here is undoubtedly the protank or coil. One day, I re-filled the tank and screwed it back on. When I press the button down, I can no longer hear the volts activating as I could before. After about 2-3 seconds I can hear a slight noise and a bit of the juice shoots out. If I take a hard puff, the juice comes straight through the coil into my mouth. Again, if I just hold it in front of me and activate it, it doesn't make any noise, as if its not working. I'm a newbie to this thing so I haven't the slightest clue what the hell is wrong. I went and bought a brand new protank 2 and a set of 5 new coils. Input the brand new setup and the exact same thing is happening. One side note, when I bought it, the guy showed me how sometimes you have to do something to the coil to make sure its catching but I cant remember what it was. I did my best to explain my problem. Hopefully it makes sense to someone??? Thanks.
