Just a thought, but the bad taste might be from the atomizer. Atomizer come primed and if you start vaping from it, it can take awhile for the nasty taste to go away. You can try holding a paper towel to the open end and blowing in the end that connects to the battery. You should get some liquid out of there. Keep doing that until no more liquid comes out, drip a drop or two of your liquid on the atomizer and try vaping again. If it tastes a little burnt drip another drop on it, but not more than 4 as you may flood your atomizer. Take a couple more puffs and hopefully (if it was in fact the atomizer) it should taste better. I have yet to find a juice that actually tastes like an analog, but the menthol does a pretty good job. Keep trying!
