I have been using 75% VG with the Minifit with NO dry hits. I’ve read that others are using more VG than 50% with no problems.Really? I've not experienced that and have 5 of them. All from ft. Odd. But the local juice I tend to recommend to folks because their entire line is delish, true to profile, inhalation tested and inexpensive is 60/40, so never any burnt hits and surprisingly no leaking even in summer heat.
