Hey guys, i've been using my igo-m for a while with no problem. But for the past two weeks, doesnt matter what gauge wire i use, rayon or cotton and any juice.or any coil at any ohm value. Im getting a funny metal taste that i never used to get. It kills any diy or retail juice im using. wicking material aint burning, there is no hot legs or hot spots. Airflow is on the coil. But still im left with a metalish taste. Any help Please?
