How do I know when to change coils?

This varies depending on factors like how often you use the device, the type of e-liquid you use (quality, VG/PG level, sweetener %, etc). A moderate vaper should not need to change coils for at least a week. The best way to tell when you need a new coil is when the taste of your e-liquid begins to change, become muted or begin to taste toasty or burnt.
