Try removing one of the flavor wicks and see how that does...
I got mine from GotVapes ( you didn't say where you got yours ) and have had no issue... and being from GV I know it is a real one from Kanger and not a fake as have been seen from some other vendors...
I vape my e-juice ( 80/20 PG/VG all the way to 5/95 ) anywhere from 6 watts ( ~3.87v on a 2.5 ohm head ) to 8 watts ( ~4.47v on a 2.5 head ) and have no problem getting plumes of vapor ( and great flavor ).
I get better flavor in the Evod than any standard dripping atty I've tried... But my IGO-L rba dripping atty does have better flavor than anything else ( including the Evod ).... As for any fiber filled carto... it isn't tough to beat those in the flavor dept. IMO
I got 2 of the evods from MyVapor store -
And no way, no how, would I try something that I need to build - just thinking about it makes me shiver....LOL
