Starting to feel like a newbie here with all my clearo questions, but they really have changed a lot since I last used them. 
Anyways, I have a ProTank 2. Had no issues on my ProVari with the connection, until I went to refill it. So, I got the Aero Base, and fixed that issue.
Now I have the hard draw issue, and the ring to adjust the airflow will not budge. Same off the device as on it. I could go get some pliers, but before I do that, how do I adjust the airflow on this thing?
Thanks
Also, while we are at it - How does the nautilus compare to this set up? I like the ides, just don't like the cost.
