My situation was a bit different... I ordered the Air 3S from DJI's web site on 12/30. 10 days later the shipping/tracking never changed, so after 3 days of chats, they tell me it's out of stock.... yea...
So they gave me the choice of a refund...
I ordered the Fly More with RC-2 from Drone Nerds this afternoon, tracking says delivery on Tuesday. I tried ordering from DJI right after Christmas and it was a nightmare. Got refunded quickly and decided to wait.
Wheter you dunk it in the Tasman, South Pacific, Atlantic or Gulf of America (LOL) salt water kills. You had better flush it with distilled water 30-60 seconds after it hits the water. Fresh water dives are a little different but they still...
