Okay, so this is how it went. I bought a Itaste Mvp aswell as a nautilus mini the other day, for juice i got from mastermix eliquid online. I got one in 0 mg and one in 24 mg. (ive vaped before, all at 24 constantly.) However when i filled my Nautilus up with the 24mg i was getting just way too harsh of a throat hit, i backed off wattage, aswell as played with the airflow and couldn't straighten it out. so i decided to mix the two, the PG/VG ratio on them are the same, the flavors are different but in my opinion they work well together. Just wondering if there was any harm in mixing them, such as shorter coil life or anything like that. Or if the only thing that really matters is the PG/VG ratio when mixing. Thank you, Onetwothreekid
