Thanks for the reply. I did watch the disassembly video.. a bit daunting.
Anyway, I poked the coil with a screw driver and suddenly it's firing again. Guess something was wrong with the coil, not the button. I have no idea what exactly, since I barely did anything at all yet magically it's firing again and producing better vapor than before.. *shrugs*
I thought it'd be strange I'd have to clean it already, since I just got it and haven't used it much yet. Hopefully I won't have to disassemble it for a while.. all those tiny little parts.....
