But this whole discussion is really splitting hairs and all my devices produce a really pleasing vape from my Snow Wolf's, 213 and Pico's with the Melo 3 Mini with cCells and my Minikin, HotCig and DNA200's with Serpent Mini 25's... I vape XXX in all these setups and I obviously know the juice intimately and I can taste and feel the difference in each tank and device...
Right now my perfect vape is the Efusion DNA200 Duo with a Serpent Mini 25 with dual coils at 40 watts.
I don't think it is splitting hairs. There is a pretty big difference. If you want real control over your vape, then the DNA is head and shoulders above anything else. Sure other boards are good, and i use lots of them. But they simply do not have the whole escribe follow through on being able to configure your device.
