I have a smok micro one and I seem to be burning through coils in about 4 days they only taste good for about 2! I have tried the .25 and .3. When I use the .3 I burn at about 36 watts at the soft setting using Vaporfi liquid max vg [yes I know the more vg the faster your coils burn] but 4 days? When I use .25 I use the temp control at about 220 with the tcr set at 105 and have tried just about every setting imaginable to no avail. I use about one 3.5 ml tank a day BTW. If someone could please help I'd appreciate it as I am very new to this only about 3 months in. But I do prefer the vape to lung method and 18 to 24 MG nicotine level solutions.
