Juices leaking comes from improper filling and also sometime is due to wicking issues. On initial use of KF, I have it too but after reading and experimenting leaking less occurs
Sometime, when I did not concentrate while filling and talking at the same time leaking occurs but can be easily manage by sucking all the juices out
Also, I had experience it if you over fill the tank, I can't get the wicking wet fast when chain vaping, seems that there isn't some pressure inside to allow juices to follow in, so I empty some out and it became as good
Just try and try you will achieve leaks free soon!
