I don't think I've heard one good story about DJI repair/warranty, but that's just what I've observed. They seem to have a knack for taking a month to replace your broken drone with another broken drone. There's at least one thread with someone in a similar situation that had 4 or 5 refurb drones sent back over a span of months, all of them had problems. Can't imagine the amount of hours and effort spent on that. If it were me I'd take the hit re DJI, and get it fixed by Thunderdrones. He is recommended by many people on this site.
