In the area of taste there are two common complaints. First of all, we often hear that the taste of e-cigarette is sometimes somewhat related. This often has to do with the coil. When the coil is empty, it often gives off a burning taste, so it is important that you replace the coil as soon as you taste it. If the taste remains the same after replacing the coil (and after having the new coil withdrawn), it is wise to change your liquid and clean the tank thoroughly (for more information, see Maintenance).
Now it may also be that the taste of the e-liquid that fumes you slightly faded, you do not taste the liquid good anymore. Some people confuse this phenomenon with a coil that is empty, but this does not necessarily have to be the case. It is also possible that you suffer from 'vapers tongue', a phenomenon whereby the person in question can not properly taste a certain taste. This can be due to overuse of a certain taste, and often happens faster with strong flavors. The advice here is to change your taste (especially if you are sensitive to this), also the fumes of menthol / mint flavors can help a lot in between.
