Becoming a real fan of cartos on Mini. When you squonk where does the juice go, up the tube to the top or to the bottom(near threads) where the atomiser is and then the vape goes up tube to mouthpiece??? When you squonk does the carto fill from bottom up or top down?? Sounds crazy but would like to know because when filling carto does one have to make sure the juice soaks all the way to bottom so when you vape the juice feeds atty from the bottom?? Thanks.
