I can tell you, with the juiceflow control closed, you can visually see an open space on top of the juiceflow holes. And you can see the 70/30 eliquid RUSH into the deck as you open the topcap. Seeing this with naked eye, I would challenge SXK’s claim that this RTA is the updated version. No matter, what SXK claims is the indication they don’t intend to fix the issue. I guess we just have to look for other manufacturers if we want to own this otherwise beautiful RTA.

Thank you FrankieS.
thats is EXACTLY ACCURATE you've mentioned about this SXK J3S rta's problem.
Other than leaking issues, it was indeed a good looking RTA.
