I have to say that I agree. I tend to taste the juices when I get them, but I also read that flavors take time to develop. Perhaps if you let them rest (and I am not sure how long that should take? Maybe need to look into it) they will mellow into a better flavor. I am sure Blu ages theirs before they fill the cartos for just this reason. So maybe if you find a VG and let it rest your chances of finding one will be better? In any case, I am not going to dismiss any of the ones I have until I let them rest a while. They may be disgusting now, but I have read that over time they actually change into what they are supposed to taste like. Maybe like aging a fine wine. Even beer needs to sit a while before you drink it right?
And my usual disclaimer: I have only been on this site 9 days, so I am reading like a crazy person trying to learn. If I am mistaken, please feel free to correct me, I would welcome it!
