I don't know. It comes out of the air hole if I vape with the air hole pointed down. I know, I know "don't do that", but that's where it sits on my evic-s where I can hit the button with my thumb. Also, if I set it down on its side it leaks. It just leaks all the time, sometimes it appears to be coming from the threads that attach the AFC to the tank. I'm always washing juice off my hands. I have a kid, so that's not really an acceptable situation. I don't want to worry about whether there is juice or juice residue on my hands if I happen to have to pick up a toy or something. Hopefully the new AFC will help, because I like the larger tank, even though it looks half empty when you turn it over.
