I've really liked my nautilus Minis powered by eVic Supreme. Have been very happy with flavor and vapor production. Have not tried IBs though.
Love my nautilus Minis too!!! However, I use an iStick and the Nautilus got even better when they went to the BVC, Great hits, vapor production and they really bring out the taste in almost any ejuice.
I soak my coils in vodka. Seems to clean them up really nicely.
Ditto. I use a hot tap water and vodka solution. Let soak for 4-5 hours, blow the excess solution out and dry overnight. VIOLA, almost like a brand new coil.
