Took two weeks of use for mine to have intermittent fire issues with the switch, about a week after I got it I looked into the v2 (dna30). Thankfully their shipping was displaying at 70+ dollars for international, decided to go with a protovapor xpv instead with the whole cost being lower and shipping being reasonable. I'll probably just replace my own switch, it being that the VS customer service were a pain to deal with in ordering the thing in the first place. Much better experience with Protovapor than with VS. (I noticed today that the shipping on VS dna30 is now $47, still twice what it was for the PV XPV at $25)
