This is my ADV and I've been vaping it regularly for at least a year now.
I don't have an incredibly refined palate, so I can't speak to the nuances of the flavors. What I can say is that this is a vape that keeps on going and tastes great no matter what hardware you vape it with and how long you've had it in your tank.
The flavor is indeed the advertised vanilla latte, but the coffee is subtle, unlike other juices that beat you over the head with it. I've vaped it at 6mg in a sub-ohm and 18 mg in a few different tanks and it tastes very rich in the sub and almost spiced in the others, with a subdued sweetness in both.
This isn't the most complex of flavors, but it's a good solid juice, if on the pricey side.
