Threads on istick 30w

[Matt Marshall]

Bought an istick 30w two weeks ago with a nautilus mini seems like the tank is screwing further and further down. The airhole used to sit flush at the front but now it sits slightly to the left? I'm concerned that the threads are knackering

That happens to me on mods sometimes, too, and yet none of those 510s have gone bad. And in my case could be the adjustable 510 on the atty got screwed in or out a bit.
