DING DING DING...we have a WINNER!!
I agree, this is what causes trouble with "dry hits" on ProTanks - but not on EVODS or even PTMinis.
I have found that removing 1/2 of the flavor wick fixes the problem for me - and I don't get any leaks - but not having the wick buried in that tiny recessed space would be a better solution.
Can you say " Protank III" ?!! ... come on Kanger, get on it! We want a Protank with the Evod's base design!!! I sure hope someone from Kangertech lurks on this site, lol.
