I got the combo about 2months ago and everything has been going smoothly. Although I had to change the coil once already, but recently it started burning my throat, I have the watt set at 5.0w which is the least it can be on, never more because it always taste burnt. Anyone know how can put the eleaf to its full potential the full 20w? My coil is a 1.8ohm. and why does it all of a sudden burn my throat I just put in a new coil about 2 weeks ago
