Just starting to notice a really annoying issue with mine. I have to click the fire button sometimes 2 3 or even 4 times before it turns on ready to fire!!. Anyone else have this happen?
EDIT: I noticed something else interesting while rewicking my Russian 91% with my current build. Originally it measured in at 1.3 ohms but today it was at 1.4-1.5 after first tank refill...Normal right ... well they talked about the .2 that the DNA30 clone can be "off".....Well now tonight after rewicking I noticed it went to 1.4-1.5 ohms when I put it back together then got check atomizer well my Russian 91% center pin has to be screwed out in order for it to make contact and it must have went just barley touching so I screwed the pin back out and boom back down to 1.2 ohm reading instantly. So it seems like this DNA30 that seems to be off on measurement seems to be directly correlated with the center pin contact at least that's what it seems to me but I'm no expert.
Not trying to sound harsh but there are at least two threads where people are giving their experience with both issues you are mentioning. For me, mine sometimes requires a second click after resting, sometimes not. I haven't noticed mine suddenly lighting up but then I only got it last night and it is in my pocket when not in use so far.
