I'm a firm believer that the quality of the juice is only as good as the quality of your device. When ascertaining mix results, the person's device is seldom or never a consideration. Even an outstanding mix will taste gross in a poorly performing device. If someone has never experienced the difference in taste between a high quality device (rba/rda) vs entry level devices or cheaply performing clones, they often find fault in the less obvious.
I didn't see where anyone asked what type device the OP was using, the freshness of the coil, battery, voltage etc...there are more factors than just percentages in the end results as to the quality of the mix/juice. What I've found (imo) is the taste of juice is mediocre to poor in all those $10 - $20 devices...juice delivery to the wick and coil degeneration being the main culprits....let alone the fact that voltage is a major consideration as it pertains to the density of different liquids.
People are always looking for advice on what's the best flavor, best pg/vg, best nic, best mix percentages but more often than not are less concerned with their devices. As an example, I know a guy that's been trying to quit smoking and having very little luck, he started vaping and has complained to me several times that he didn't like the taste of any juice. I took a look at his setup...a Kanger Evod starter kit...I pulled his coil and it was so gunked-up the battery would barely if at all deliver any heat to the coil. He was right, his juice tasted awful...nasty, burnt disgusting. He simply didn't know any better. I put in a new replacement coil I had, filled it with a juice I had mixed and let him try it. He said, "now that taste a lot better"...then I let him try the same juice I had in my KFL that had a week old build and he said, "d-a-m-n, there is no comparison, why does your's taste so much better than mine" ...some may say I'm F.O.S*it...those that have compared will know what I'm saying is true...
That could be, but right now the setup I have is all I can have. I've spent all the money I can for now. I am using a Vision Spinner 1300 with a Kanger Mini Protank 2. I always keep my coils clean and have been rebuilding as well, so I know its not build up of gunk. I do want to buy another setup sometime in the near future, but that is going to be hard to pick! What does KFL stand for?
