ok i got one of the orginal darwin first batch. Everything worked great for about 6 months then my unit would stop turning on. i sent it back twice each time came back with same issue. Finally told Brandon to just send me a new one. and now the new one does it too! im getting really frustrated. is anyone else having same problem? sometmes it just turns off and other times it wont turn on. I flip the arm up and nothing, flip it down then back up and it turns on.....wtf?
