I have had the kanger e smart for about a month and I keep getting a weird burnt taste when i use it. I tried cleaning it with warm water and dry burning for about 10 min and until no smoke came out of it but all i get is a burnt taste and no flavor from the e liquid. It has a 2.2 or 2.0 ohm resisitance i think and 3.7 voltage. The clearomizer it comes with doesn't have a removable head-it's all metal around the air tube part. All 3 clearomizers are giving me the same burnt taste. What could be causing this and is there a way to fix it? Can you over dry burn the coils? This was the first time i cleaned it so i did it until 5 min after i saw the coils glow. I'm worried that the vapor coming out of it may be harmful to my health?? because i'm not sure what's causing the taste. From what i've read most people said cleaning it would solve the problem but i also saw that if the ohm resistance is too low it can also cause a burnt flavor? I'm confused because this is the clearomizer that specifically comes with the e smart so i wouldn't think there would be a problem. This is very discouraging and is totally ruining my vapor experience. Any help as to an explanation or what i could do to maybe fix it would be great. Thank you. Everyone here has been so awesome and so helpful to a newbie with lots of questions.
