Apparently,I don't understand something here.Is the Wetbox really compatible with the no-filler cartos?Where does the juice go when you pump it out of the box.Seems to me like it would end up above the fill holes.Does it then dribble down thru the little holes into the fluid chamber?OR am I totally full of s#&*? LOL
The extra juice goes into the E2's tank and gets used from there. No back flow at all. You get the atty flavor with a cartomizer!
