I re-wicked mine today using Labo cotton from amazon, its like KGD... not any cheaper or anything, but I have this must try new things syndrome...something tells me I am not the only one in this thread that suffers from that
anyway, I didnt put the wick ring holder thingy under the chamber...no difference in wicking or vaping... just thought I'd mention that.
also I have to say to the poster who is having trouble getting his/hers to wick or stop flooding, its obviously a bad device, or some piece is not milled correctly, or oring or something..... I have wicked this thing 3-4 times, done 2 coils so far, with the exception of 70vg juice it wicks just fine wide open.......the higher vg juice I had to close the afc a little to get some pressure to pull the juice in, but I have not had a "bad" build yet..... with the exception of having to trim the wicks like a hair stylist, its not much different that wicking a kayfun or maybe an aqua might be more accurate.... so far mine just works. If I close the afc with 50/50 juice I get a little wetter vape (more flavor) and maybe some slight (I mean slight) gurgle or slurping noise.... but a great vape. No real complaints from the one I got with the exception of the 510 pin being too damn short
I will probably order the $15 from fasttech if it has a large pos pole for more airflow that might be nice.... I remember why I didnt order that one, its a 10 day wait

just need to order it and forget I did and it'll show up whenever it gets here.
