and i maintain in real life it doesn't make a darn bit of difference....(and a dna20 adjusts in .1 increments not .5). what's on top matters way more than the power source. vape what satisfies you, not anybody else......
At the end of the day the only thing that matters is the smile on the face of the person vaping. All of this is subjective and relative only to experience.
If I am not mistaken the DNA20 is a chip for people who make their own mods, there are some limited mods out there for purchase that are built with it?
I would rather buy something to use and spend my time working on my collection of 60s and 70s gas guzzlers or playing with my computers/video games
