Hey guys can someone please enlighten me on the difference between the dna 40 vs dna 40D? I just pulled the trigger late last night on the Vapor Shark dna 40 then of course today I noticed the VS rDNA 40 says it has "the DNA 40D under the hood". I guess all im trying to figure out is did I just purchase the older DNA chip from VS? Is there any benefits to getting the DNA 40D? Thanks in advance and Happy Easter!
