taking the deck out is not the greatest idea unless you want to check on the coil or wicking.Just out of curiosity, how do you fill from bottom? Take out deck and then what? Probably a stupid question.

then have some paper towel ready its a little wet when you take it out.
just open the juice flow you will see it when you take the bottom off ,two elongated slots.
they got to be open when filling! when full srew the bottom back on and close the air ,juice control to where you normaly vape ..that's all .
