My setup is the Augvape Merlin Nano MTL RTA, with the Eleaf Aster Mod and the ArcticFox firmware, basically turns it into a DNA.
Sanyo NCR 18650 GA 3500mAh 10A as I don't vape over 20w and the VandyVape Superfine MTL Fused Clapton 1.51Ω Coils.
Also use Cellucotton/Rayon and mainly vape NicSalts.
The thing is small and vapes like a champ and very cheap to run. For the price this tank is a must have for all MTL users. Its as good as any Pods out at the moment but as its a RTA you can get the cotton and the coils for next to nothing. For the price of a pack of pods/coils you could get a years worth of cotton and coils and its really not that hard to build on.
