Mine is indeed a demo model. Its still my daily vape and I haven't experienced the kind of Flux I had with the ipv2 but just some minor movement. Like . 3 reading at . 5 at worst. But on my kayfun and Orchid never an issue. Double checked just now with the pin out and same thing. . Weird is all. But the good thing is sigelei has been in the game a long time. I'm not worried about it all that much.been running @ .4 since day one with no fluctuation, yet i'm not changing out Atty's; i set it & forget it....everything's nice and snug.....man i sure hope i haven't jinxed myself...
didn't you say yours was a Demo Model......sure hope for all of us there is no chip issue......so far i'm loving mine the vape is just so intense @ 50 to 60 watts compared to anything else i use.....very satisfied so far.
