A few misinterpreted facts need to be pointed out here...
There is nothing new or revolutionary about 510 device air flow controllers.
This one is in combination with a replacement pro tank base, instead of being an add on device you screw your 510 connector
(pt base) into.
This one fits all the pro tanks... the pt1, pt2 and the pt3.
The aero tank has this feature built in and the aeero tank is all stainless steel construction.
The aero tank is made for the pt3 dual coil head and it does NOT accept the old pt2 heads.
This device lets you control the airflow through the kanger head/coil, but it will do nothing about fixing the new air flow issue the 510 connected kanger devices are now having with the new soft silicone insulator grommet on the newer kangertech single coil heads.
One good cure for that problem however, IS to replace the damned kanger 510 pro tank base altogether with a protank mini base !
This option gets rid of the captured grommet in the 510 connection and lets the protank operate with an ego connection, thus eliminating that damned problem altogether. You may need to add one silicone coil stem cup upside down on top of the existing coil stem cup to get a positive seal on the driptip tube part of the tank as I did. It's working great now without the damned choked off airflow grommet issue or the usual pt2 gurgles.
Meanwhile, kangertech does have a remedy for the soft grommet air flow problem that they have been using on the pt3 heads center pin. I expect that they will be adopting the same fix on their future single coil heads too. see attached link to the grommet airflow issue discussion.
