Good job as always Vic.
You omitted, deliberately no doubt, that there's an AFC for the Kanger Protanks ... the PT3 v2 also takes the Aerotank v2 AFC.
£2.99 and £3.99 respectively ... turns the PT3 into an Aerotank performance wise and overcomes the issue of no airflow slot in some devices.
The glass tank for PT3 and Aerotank is identical, the Aerotank's stainless tank also fits the PT3.
