Vape coils for e-cigarettes
Mouth to lung E-cigarettes use coils that are heated up to vapourize the liquid poured into the atomizer
These coils need to be replaced every so often. Burnt coils will usually produce a burning sensation when inhaled and it is advised to replace the coil every so often. A fresh coil has a more distinct transfer of juice / e-liquid flavour when the vape is inhaled.
Please be sure to clean the atomizer, glass and mouthpiece when replacing the coil as the previous coil could have left behind some burnt juice or cotton, influencing the taste of the new coil.
