I really want to like this tank but I've tried several different wicking methods and it always results in leaking to some degree. On the official Facebook page people have a lot of suggestions, tried them all and still leaks. I've actually started to use it like a dripper and only open the juice flow when i'm vaping it and then close it otherwise, even this still results in a small amount of leaking. When i take the cap off to look at the deck I can see it's flooded. I'm starting to think it is a design flaw because I've have a few other gravity fed tanks that never leak.
