Just got one and no matter what voltage and what resistence coil I use all burnt taste.
Ego-T vv battery.
It helps to put a couple drops right onto the coil and wait a while before vaping it. Also make sure to keep it relatively full. Most of the time the burnt taste is from it not getting juice. Tipping helps.
