Oh, something I personally believe, for better or worse, your juice should taste how it smells. End of story. I have like 20 juices in front of me that, when they taste their best, they taste just like the juice smells, but in vapor form, so slightly sweeter and just a tadmore "open" (less concentrated, but still just as solid and strong... Good thing none of them smell like perfume, but then again, I never buy I juice before I test it.)
Sometimes there will be an added note or two, but really, if you open a juice that smells like a rich bag of moist plums, and it tastes like cardboard, smoke, or charcoal, even if you do enjoy the taste, that's not how that juice is supposed to taste; it's something wrong with your atomizer. If it benefits you, that's good, but it really isn't what vapor in it's true form is supposed to be like. Vapor should pretty much be like hookah at worst. No "butts" about it (ha, since I taste cigarette butts with half these devices...)
I think that's the vaping standard that many on this forum should open their minds and equate to when it comes to helping new members discover what is the "standard line" for what most people expect out of a vapor. We all have personal preferences, but if some of us do enjoy some pretty odd tastes, I don't think we need to forget that it isn't the norm. We don't need to keep telling new members they're doing something wrong (it's quite hard to ruin a good atomizer, believe it or not...) and try to ask ourselves why it is that products, obviously designed and marketed to newbies, aren't performing.
One thing that runs through my head, like with my iClear 30 experience, I think "What if a politician were to have tried this very head? They'd have written up a bill to ban these devices in a hot second!" because the taste was so poisonous. I've been a smoker for years, and yes, if I happen to burn a cigarette filter, it does make me physically gag and throw up, but this iClear head was a burnt cigarette filter times 10. It was downright as though I literally lit up a cigarette filter and took a huge, big draw.
To this day, I don't know what caused it, but I know that it's not right. Things like that shouldn't be happening on such a wide scale - who ever did a study on the health effects of burnt "whatever" in e-cigs? That's what worries me. Who ever did a study noting the health effects of someone repeatedly throwing away cash on heads that perform like this? That's what worries me. Who ever did a study on how many people quit vaping after experiencing something like this? That's what worries me. And that's why I think this quality standard needs to improve.
