We've ordered over a dozen of their flavors now, and never gotten a bad one. We have had one or two that weren't favorites, but it wasn't due to the juice itself, it was just we realized some flavors we'd rather eat, not vape. I'm currently running 5 different tanks of juice, and KBV is in all of them. We keep multiple bottles of Blackberry Ice Cream, Peppermint Ice Cream, and Crisp Cola on hand at all times. We just recently got in a 15ml bottle of the RY4, and it's the first tobacco flavor I've ever tried and liked...it's almost gone, and I plan on purchasing another bottle. I have a simple setup compared to most...I just use an ego and stardust tanks.
Taste is an extremely subjective thing to start with, then add in days the taste buds are acting up, what type of equipment is being used, the age of the juice, how high the nic content is....and everybody tasting the same juice will taste something completely different. We tried out many really popular vendors before settling on KBV. For whatever reason, the juices from those vendors just didn't work for us and the equipment we're using, at the nic level we vape at. We'd never say they were bad juices, because as many followers as they have, they're obviously not....for whatever reason they just didn't hit that sweet spot for us.
Maybe KBV just doesn't hit the sweet spot for your vaping needs, and that's perfectly ok, but that doesn't make them bad by any means. The flavors you tried are very popular flavors, you could always try reselling them, or trading them for something you might like.
