Sorry, but you are well wrong there. You are not so mature and clever that you are not swayed by presentation and design, we all are it how are brains are wired. Something could be the best product in the world, but if it looks shit or is poorly marketed it will be a commercial failure. We all like to think that we are smarter than the marketing men, but we aren't. If I look at the packaging of this ejuice than I am automatically thinking it is going to taste of Fanta, so if I like Fanta I am already 50% of the way towards buying it. It is marketed at adults. Adults like novelty items. Adults like stuff that makes them think of their childhood. Adults like Fanta just as much as kids do. On my desk right now I have flavoured juices that could be described as kiddy flavours...
Shark Gummies Red
Shark Gummies Blue
Raspberry Ripple
Strawberry Mousse
Cream Egg
Milk Bottles
Fruit Slushy
Sherbert Dumbledore
Parma Violets
Lemon Sherbert
Pink Glazed Doughnut
Strapplekwi
Toffee Sauce
Based on the logic that these types of flavours make vaping appealing to kids they should all be banned and the juices only available should be tobacco and flavourless. But nobody actually wants that. My avatar is Superman vs the Evil Nicotine, when I was a kid the cartoons and posters of Superman vs Nicotine were everywhere, I loved Superman (still do) but those adverts designed to appeal to kids did not stop me smoking. The only reason I smoked is because my mate Kevin did, because his big sister did and so on.
No vaping product is directly aimed at any particular one group, they are aimed at humans that like nice things, which is everyone.
