I'm very confused about how to rate this. I'll start with my first impression. Vader tastes like dirty gym socks that ignites a fire in your throat immediately after inhaling. The throat hit from this juice is pure hell.
However, after mixing 50/50 with pure VG, it actually has a good flavor and is toned down A LOT. It also seems more true to the advertised nicotine content after mixing with 50% VG, and to me, that's a problem.
On one hand, I now have a 30 ML bottle of a decent vapable juice. On the other hand, I shouldn't have to alter it to make it tolerable. I'll finish this bottle, diluting it of course, and after it's gone, I hope to never see it again.
