I've wicked the merlin 3 different ways. First was with the wicking jammed into the well, seeing the wick in the
juice holes...it seeped.
Second was the same technique as the first but had some outside the well so maybe it was dripping off the coil, filling up the other area and seeping down the airflow...it seeped.
Third was not having the wick in the well but ontop so the well was empty and having the JFC only open a little bit...it seeped.
The third way IMO is the best for vape quality. I been wicking attys for over 3 years now and the seeping isn't a wicking or coil issue but a oring and/or not holding vacuum issue. This merlin seeps enough to to go 1/2 inch around the 510 then enough
juice to go all the way around the door panel seam of my IPV2 and then leave a square juice ring on my desk, that's a lot of juice seeped just for sitting overnight, it all adds up in time to wasting more juice than the merlin is worth.
