So far loving the juices I received last week, though I'm sure extra time to steep is needed to really get the most out of them. Haven't filled any sort of tank with them as I'm really just trying to get a sense of the flavors with an atty, first, and go for 30ml bottles on the standouts. Without going into a full out review, a few things I can say about RAWR juices so far.
They need to steep. Minimum 4 days before I really tasted what Mike must've intended for them to taste like. At first I was a little disappointed that the flavor I was expecting was hardly there, but that's changed drastically since day 1...
But, once they've been allowed to sit (Truth Serum, Green Peach Tea, in particular), they're so spot on! A pig plus is that none of the juices, even the Razmatazz, is overly or artificially sweet, just accurate. There's a smoothness (almost creaminess) to the vape which is great and refreshing and something I'm not used to in other juices I've tried.
They vape well when you kick up the voltage a big though not too high. Past 5V it starts to taste off even with 3.2ohm attys. Not burnt, just not right.
Vapor is pretty good for a 50/50 blend which is great and unexpected.
Can't speak to throat hit on any of them as I vape at such low nic levels that I'm hardly the best judge of TH. But it is satisfying for me.
Not as much of a fan of Screaming Mammaries as I hoped to be. It's missing just a bit more espresso to match the milkiness so that it's more like a cappuccino flavor. Don't get me wrong, it's one of the smoothest and more realistic coffee vapes I've had to date, but it's like the barista made a latté by mistake, a good one, just not what I asked for.
And still the biggest surprise was how good the Chocolate Dipped Nana freebie tastes. I would eat the vape if that were possible!

I might even kick this up to 12mg nic and definitely will be ordering a 30ml of this. I asked Mike if he could throw in a desert flavored juice as the freebie (never had one before) and man did he get it right!
Overall, a fan and a returning customer. Looking forward to the fact that these things will only vape better with time. Glad I switched to dripping lately. Only bought 10ml bottles so trying to stretch them out for as long as possible
That said, I'm worried about what a stardust/nova will do to the flavor (not into cartos), so this is pushing me towards rebuildable atties like the Penelope/Oddy/Phoenix that can hold more than a few drops at a time and promise the best flavor. This is not good for my wallet...
