It's senseless to judge a person by what he's selling. Who cares? I am 100% sure Elon doesn't. I am 100% sure he doesn't even remember anything related to this at all. It 's not like Elon toiled away to give the OP a very thoughtful and personalized gift and now he's trying to flip it.
It's not much different than selling a founders/signature series Model S. Then of course that would be an actual functioning as opposed to this non-functioning powerwall....
