Question: how do i know when i need to change the coil in my vape?
Answer: A burning taste. Vaping a dead coil will eventually result in an acrid, burning taste. ...  Gurgling sounds. Vapes shouldn't gurgle. ...  Weak or “off” e-Juice flavor. This often precedes a burnt taste. ...  Low vapor production. The vapor produced by your coil will gradually lessen with time.
