I have owned my ITASTE V2 for just over 2 days now, but I have been running my very loved Kanger Aero Tank on my E-go twist for over 2 weeks. I just started my second 2ohm coil yesterday due to fade.
One thing is for sure I have not gotten any juice to back up into my tip (AKA "Leak by"), there's hardly any gurgle, and there's been Zero leakage past any of the seals.
I have messed with the Air flow settings, but I always find myself going with the tank wide open.
Another thing worth mentioning is the coils for these tanks have been holding up very well to higher Voltage/Wattage settings 5V/11W.
There's plenty of smoke to please anyone and when you figure that you can have both the, ITASTE MVP V2 plus the Aero Tank for under $100.00 would have to say it's going to be difficult to get a better setup at that price point.
FYI I smoked Tabaco for over 10 years, I may miss it but I NEVER enjoyed it as much as vaping.
