• Make sure a new coil is properly primed and setup for use, thicker eliquid like pure VG requires more priming. 


• Replace the coil if it is old (more than 7 fills). 


• Make sure the tank does not run dry, this will cause a dry burn and the coil will always taste burnt there after. If a coil is allowed to run dry the cotton overheats and is burnt, this is referred to as a dry burn and taints the taste of the coil. If using Turbo coils be very careful of this and refill before there is any chance of running low. 


• Do not try to mouth inhale a direct lung coil, this will result in a burnt taste as there is not enough airflow being produced. The lack of airflow means the coil overheats and burns.
