It's not bad, not particularly good, it's just nothing special. Your run of the mill "tobacco" flavor with some hazelnut or some other kind of nutty flavor in the background. The tobacco is not a rich tobacco but a generic "what the hell is that flavor" kind of tobacco.
If there is a custard here I can't taste it at all. Same with the vanilla. All I get is that generic tobacco flavor with some nuttiness. It's not particularly fun to vape this juice so I'm going to put it in the closet, let it steep for a few months and revisit it. If anything changes I'll update my review but I highly doubt it will. I've had this sort of flavor before and this is usually as good as it gets.
If you want a FARRRRRR better version of this type of flavor check out Vgod's Cubano Black. It has a much richer tobacco (like a cigar, and you can taste it), a nice custard element and a pleasing level of sweetness. Their regular Cubano (the brown one) is decent but average, and reminds me of this VTC juice from Ripe Vapes because it has that undefined generic "tobacco" flavoring in it too.
All in all, nothing special. Maybe if I had never tried Cubano Black I'd rate this a 3 but on juiceDB a three means it's above average, which VTC is not in my opinion. It is the epitome of average.
