You who have actually gotten their drone covered under their warranty are lucky indeed. First thing you get back from them is pilot error. In my case, my P4 flipped inverted and powered into the ground from 200 feet! No external circumstances at all. DJI said no warranty. I kept on for a month, still nothing. All I really wanted was to find out how it could have flipped over since they will immediate correct any level other than flat. Still they refused. Nothing I could provide them convinced them that it just occurred the way I stated. I paid the repair bill hoping to get my drone fixed and back soon. I even was able to follow the test, repair, test again, and shipping back to me, however the serial number changed at the shipping stage. I finally got them to admit that my original drone was not repairable and they sent me a new one! They still refused to explain why. Then, they asked for the flight logs, etc. None existed as that flight mysteriously was not recorded anywhere I could find. The immediate flight and the 4 flights after the crash were there but not the one of the crash! They then said there were no flight data information on the internal memory in the drone so they could (would) not honor the warranty. OK< so enough tried, got my new P4 in and guess what? Someone had taken off the four retainer springs that lock each propeller on the motor. I called immediately and was told I had to send in a video showing the missing parts!!!!! Even after that was done, still no replacements came in. ONLY after five more weeks and numerous phone calls and emails did I finally get them in. So, that alone proves to me at least that DJI cares absolutely nothing about their customer base. Apparently their markup is high enough and their new customer sales are enough to keep them growing without worrying about the all important repeat customers. So, all who got their warranty honored, you are fortunate indeed!
Thanks for reading all this again.
