One for ProTank fans :)

Actually, that depends on the travel to the contact point in the airflow control - the issue with the silicone grommets you describe is the grommet getting squished and expanding to block the airflow - since the distance between the airflow control and the bottom pin of the ProTank head is now fixed (as opposed to varying based on the PV you're screwing the PT on to), the airflow control may well fix that too.

I hope you're right Aegis...ordering one asap

Bought one for my father since he got virtually no airflow when connecting the Protank 2 to the Nemesis. Received the item on Monday, attached it to his Protank 2 and it fixed the airflow issue completely. Now the airflow control is done by the new tank base instead of the airflow control on the nemesis. I also noticed that when my father used the Protank on the Nemesis without the new base, it would flood really easily due to the 510 connection holes being blocked and the only airflow is through the center pin hole, forcing the e-liquid to go through the hole because of pressure build-up caused by the lack of airflow. This is usually the most overlooked culprit for leakages.

Solid product overall but it does have one issue, the airflow control ring is sort of loose and will not stay in place. So if you were to carry it around in your pocket, the airflow control ring will most certainly change its position.

TLDR; Having some airflow issues with your device? Get the ACV (Airflow Control Valve) from Kanger, and it will fix it.
