I came across something the other day that peaked my curiousity. I had read an ad for an Aerotank base that said it would fit the PT2 and the PT3 which would allow you to control the airflow of your atty. I thought "heck, why not?!" So, I ordered one and it came in yesterday, which then went directly on my PT2 and it works great! You can adjust the airflow from barely being able to pull a draw on it, all the way to almost no resistance when you take a draw. In my humble opinion, it is worth the $5.99 to add this feature to my favorite tank setup, the wonderful PT2. I just wanted to let my fellow "vapesters" know that it indeed does fit and work as expected, and I am digging it....... GIVE IT A TRY!!!!!!!!
