Just in the interest of getting accurate information out there...
Last Monday I dropped my Mavic Air. It was off, it just fell three feet from my open bag onto the ground.
Next time I tried to fly it I had multiple errors (IMU, accelerometer, gimbal) and trying resets & calibrations didn't work.
So on Monday afternoon I created a repair ticket on DJI's website, and sent them the drone via UPS.
UPS Delivered it to them on Wednesday.
On Thursday they diagnosed the problem and sent me a repair authorization request. I paid, and by the end of day Thursday the drone was repaired.
Today, Friday morning, the drone is with UPS on its way back to me.
Based on all the "horror stories" I had heard about DJI's support service, I was expecting it would take 4-8 weeks to get my drone back. Instead DJI received it, diagnosed it, repaired it, and shipped it back to me in 3 days!
