Hmm... can't say I ever had issues with the Nautlius 2, but I was pretty careful with it. No overfilling, the coil does need to be tightened down, but everything else, not too tight. I'm fond of my zelos mod but I really only use it as a backup. No issues so far, but it always amazes me how different these tanks can be. I know there are a lot of nautilus original fans and I got one for a great price and initially thought it was a clone (so pretty, though) but it wasn't, it just leaked like a sieve. Since I preferred the vape on the N2 anyway, I didn't do much trouble shooting, but I guess everyone's different...
Good luck with what you try next, if you can't get the issue resolved.
