There's no such thing as a 'dud' on our product line. Because taste is highly subjective it's possible (but not probable) that you may find a liquid you don't like. The liquid that remains on our product line has "passed the test" and is pleasing to the majority of people who purchase it. We go to great lengths to describe the flavor profiles of the liquids that are less than self-explanatory striving to deliver on the "what you see is what you get" philosophy. Mixing liquid is a culinary art and we take pride in offering only the best. WE WOULD RATHER PRODUCE ONE AMAZING eLIQUID AS OPPOSED TO MAKING 250 FLAVORS WE HAVE NEVER TESTED OR TRIED! For every flavor we offer, there are 2-3 that we have rejected because they aren't good enough for our customers. We cut the "fluff" and opted to hand-pick our permanent offerings based on extensive customer feedback and testing. Again, there is no guarantee that you will fall head-over-heels for our liquid... but we know (statistically) that your chances are better here than the alternatives. You can order ANY liquid from this site with confidence knowing that you will probably enjoy it.
