The
coils that actually shipped with the nautilus mini lasted longer than 2 weeks each. I am using the same liquid, watts, and frequency. I've done a bit of research into making coils last longer using the methods already mentioned and nothing seems to work. I can only conclude its the
tank or the coils so I am simply going to switch out both of them. If the problem remains this too is good information since I have more data to go on. At that point I will try the rebuild-able coils. For now, I will grab the first thing that atleast two people recommend
