Probably more user error than anything.... I have the one with the removable drip tip, got it friday and I'm on my third head already due to, what I take is flooding.... it eems worse at night.... draw seems to have some resistance and then a bit of gurgling.... there always ends up being liquid under the drip tip, but nothing makes it to my mouth.... taking the entire tank off and blowing through it pushes a similar colored liquid from the head.... not exactly the juice, more like its watered down.... condensation or saliva running down the drip tip to the atty, I assume.... but today, every draw has that freshly cleaned wick that wasnt allowed to dry watered down taste, even my stock ego system that is impossible for saliva to reach the atty.... if its saliva, is there any kind of filter or something to use inside the drip tip to keep it from etting to the head? Or somehow not visible, water from the air is condensating inside the tank diluting the juice? Unlikely given how often I'm topping it off throughout the day....
