So i'm fairly new to vaping, only about a month, so i'm still learning what everything is/means, i've been using a "compact ego rbc" with no real problems until the last 2 days. for the last 2 days almost every hit has been a horribly disgusting burnt taste, i've cleaned everything as best i could, and replaced my coil 3 times now, every time i get like 3 good hits, and then the same horrible burnt taste over and over. please help
