Im new to vaping, I started about 3 months ago. I have a drag mini and i have a problem where ive wasted so many replacement coils because they keep tasting wrong. And im doing everything that everyone says is the right way to change out a coil. I even had someone thats been vaping for a while change it out and still tastes wrong. I even bought a new tank (mesh pro) and it tasted good one time then went back to tasting weird like burnt. I dont know what is happening and ive wasted so much money on coils. Has anyone else had this problem or know how to fix it?
