apparently vaporshark considers the dna40 a 'mech-mod'.
No wonder new vapers are confused.
I suppose it's to the suppliers (superficial) advantage to confuse new customers.
"Vapor Shark now caters to the more advanced, tech savvy, vapor lovers with our advanced product line.

I actually like this header. I just can't see a new vapor wrapping up some nickel to take advantage of the dna40. Don't believe anyone has prebuilt ni coils. And VS has a really nice disclaimer on each page saying its for experienced users with extensive knowledge.
