I opened up the air flow to see through the tank, then filled with my wife's chocolate peanut butter up to that area. Next thing I know we got juice going all over. I think she might have opened the fill holes while trying to adjust the air flow and puffed it. Or is it overfilled at that level?
Well not knowing how "FILLED" Ya' filled the tank I don't know (BTW: I always leave it a little "shy" before I get to the top) . . . However, I will say that from "My" limited experience, it is very easy to open the fill holes when adjusting the Airflow control . . . Matter of fact, as I mentioned in "My" earlier post, I had a very difficult time - not only finding where the Airflow control actually was (Just below the APEX Logo) - but adjusting the Airflow control without opening and closing the "Fill Holes" any time I moved the section . . . SO - I would suggest mentioning to "Wifey" in the future after adjusting the Airflow to look and make sure the fill holes are closed before Vaping . . . Just Sayin' . . .
