I KNOW!! Excellent question, and one I've often wondered about. I have absolutely no idea why tastes vary so much when it comes to vaping. It's so weird.
I have a couple of juices that got awesome reviews on the site I bought them from, and people just raved about them, but they were the most vile tasting flavours I've ever tasted. I can't understand how anyone could vape 'em and say mmmmmmmm....and then rate it 10/10. ????!!!! Come on! I mean I can understand something like a coffee liquid - some like theirs a little creamier, sweeter, or black, so tastes are going to vary, but it should always taste like coffee! It shouldn't taste like really filthy, sweaty feet!!
I'll never understand. lol.
