My Darwin is intermittently firing all by itself. I have to flip the arm down after every vape to keep my atomizer from dying. I figure it's something with the logic board and I'll need to send it in for repair. I sent an email to Evolv about getting it repaired, but I haven't heard back from them yet. Does Evolv do repairs on Darwins? If not, who does? I bought mine used, so I can't go back to the supplier for help.
