i'll try to remove the o-rings and see how it goes. It looks like it's leaking only with the attys, but not with a carto. I tried with a I6 at 6V, and is much better than on I3 - on I6 i do get a nice TH.
also can someone tell be what's the difference between :
GG i6 AFSv1 iAtty - 901 - Cloud 9 Vaping
and
Vapor Kings - JOYE 510, JOYE EGO, DSE801, RN4072, DSE901, RN4075, RN4062 and KR808D-1 e-Cigarette batteries, atomizers, cartomizers, e-Liquid, accessories and more!
they are both I6 but VaporKings say they are for AFSv2 and Cloud9 say they are not ...
confusing ...
The link to the one on my site that you've specified there is a Version 1 AFS iAtty that only works in the v1 AFS, not the V2. I don't have any 901 iAtties of any kind in stock at the moment anyway.
