After
vaping for hours on it I occasionally get a burnt taste with the 1.8 ohm coil at 3.2 volts. Loads of vapor though. I have used it with a 2.2 ohm coil and did not get the occassional burnt hit with it. I am using it on a joytech ego c twist. I overall very much like this. Tons more vapor than my Evod with little effort on drag. I am using a ry4 blend which is 50/50 at 18mg of nic.
Overall I can see this being my main
tank due to capacity and vapor production. Just keep volts low with sub 2 ohm coils.
