Just a confirmation of the previous suggestion (by Flier, I think) to use a dripping atomizer for testing. I also suggest getting a good one, preferably an IkenVape if you can catch them in stock, and close to the resistance of the cartos you'll normally use. This is the absolute best way to find out how a
juice is supposed to taste at a given voltage & resistance. Also it has the advantage of being easy to clean out & reuse with a different flavor, and requires only a few drops of juice for a sample vape roughly equal to a cigarette. This can keep you from filling a carto with a liquid that needs to steep for 2 - 3 weeks before using; you learn in 8 - 10 drops it's either not for you or not for you *yet*. And a good, well-maintained atty can last months for testing purposes.
Best of luck & Happy
vaping!
