The Herakles Mini-RTA is identical to the Herakles RTA-2 in every way except eliquid capacity — tank design, build deck, air flow, and top filling are all the same; the only difference is that the Mini-RTA holds 3 mL versus 6 mL for the RTA-2. As a result, performance is identical also — which is to say, brilliant.
Sure, all three Herakles RTAs (the RTA-4, RTA-2, and the Mini-RTA) can produce voluminous, thick clouds of vapor, but where they really stand out is with flavor, especially the Mini-RTA. The entire series represents three of the best RTAs on the market.
The only downside to the Herakles Mini-RTA is that it’s the same price as it’s larger brothers, but that’s hardly a gripe, since the tanks are essentially the same.
