My screen went out about a week after I got my v200. No reply to multiple emails to Hana. My ohms are also all over the place now. Watching on Escribe it either goes back to default 8.5 watts or shoots up to 150-200 watts and smokes the coils. The screen on my V200 is actually falling into the device. I guess as of right now I have a $200 paper weight.
