When I put a new atomizer into my Aspire Nautilus my Joyetech Evic displays it correctly at 1.8 ohms. I have found that over time the Evic will display that the atomizer has changed to 1.9 ohms.
Furthermore, now that I have used the Nautilus for a few months I instantly get an initial reading of 1.9 ohms on a brand new 1.8 coil that I insert. I keep the voltage pretty low and do not fluctuate it very much.
The other issue I have found is that the Nautilus tank sometimes forms into a tilt to the point where the airflow ring can be slightly moved up and down. I was able to fix this one time by taking it apart and applying pressure on it until I heard it snap back into place. I am just wondering why this happens and what is the correct way to fix it.
And just one more - Sometimes I find that due to the large size of the tank my e-liquid goes stale before I can vaporize it all. Any suggestions?
