Got my new setup today, an iStick 30w and Kanger ProTank 3. Unfortunately, after getting it setup tonight, I noticed that there is hardly any airflow (lots of restriction) and also it leaks where the tank and battery connect. When it was reconnected I got a little juice on my tongue when I tried to take a hit (luckily I was gaping 0mg) anyway, what is the best fix for all of these issues? Thanks again!
