Again, from Wayne at heaven gifts - Kanger techs say that there has been no change in the number of threads on the T3. However, in my experience, threading from Kanger has been, as I describe as 'crunchy' - with earlier cartos and for the T2 mouthpiece. But all my T3's from hg, good prophets, so far, don't have the gap on joye eGo-c's, that has been mentioned here.
