Hello all, I have a MVP v2 and recently purchased an Aspire Nautilus tank. I am noticing a decreased coil life suddenly. My first coil, the 1.6 ohm that came with the tank, lasted about 9 days. The second coil only lasted 4 days before showing a resistance of 3.0 ohms. My third, and current, coil I purchased on Thursday and am currently reading a resistance of 2.8 ohms. I have been vaping at 9.0 volts, not sure if that's relevant, but just to have all of the info out there. Is this a potential problem with the MVP itself, and is there anything I can do to increase the life of my coils? Thank you in advance!
