FWIW, I have a Nautilus Mini and have been using Virgin Vapor 100% VG juices in my tanks (I have 2 Nautilus tanks + several "other" tanks) with no problems.
I have seen other threads here where folks say not to use 100% VG juice in their Nautilus or the coils will burn up quickly and I just want to point out that is all depends on the company that makes the juice. Coils may burn out with other 'thick' 100% VG juices however that has not been my experience with Virgin Vapor or Ben Jonson's eJuices 60/40 VG/PG.
I run my Nautilus on a Sigelei 30 Watt Mini between 7.5 - 12 watts and coils are lasting me a minimum of 3 weeks. No power vaping and no cloud chasing. I vape like I used to smoke analogs.
I hope I am not violating any rules by mentioning "brands" of eJuices here or the brand of mod I am using. I did not specifically see any rules against it.
I am in no way trying to start any arguments or anything. I am merely trying to point out and pass along some good info (suggestion).
I would also like to read other peoples experiences with juices and the ratios that you are using with your Nautilus as well.
