I agree interesting as mine was 70/30 pg from freedomsmokesusa. I dripped 3 ml's in stages and let sit for a couple of hours...would not wick. When I took a little filler out....wicks great and enough vape to fill a room...amazing
How did you fill yours?
I drip right into the filling and because I lack patience I usually end up getting some down the middle as well. Not sure if the liquid getting into the center has anything to do with it but it is probably easier for the carto to wick when the center is all ready wet. Could also just be variances in the manufacturing.
