I have been on a lot of forums for some time - and as a result I have heard a lot of horror stories about DJI customer support. Her is a small story from another side of DJI
Posted this on DJI official facebook site:

"Need help from the group. Few days ago my flight records started to act strange - they will not sync - . I get this message : Sync Failed , Please try again. Some of the flights sync - maybe 2 out of 4 when trying to sync four flights. I have all the new FW + SW iPad air 2. "

Promptly I was contacted by a DJI representativ that would help me out the next day.

Next day come and I was asked to upload my flight records and they where looking into my problem

Today I could post :

"UPDATE - I have got excellent support from Dji Terry - it seems like there has been a small error on a server. Now I can update my Flight records again. This should really have been a new thread as most of the times we only hear of bad customer service from DJI - this is about just the opposite - VERRY GOOD"

This is of course a small example from a not to big problem - But still - I think DJI support is on its way to improve a lot.

After trying to resolve a video issue I've had since purchasing my inspire, i resigned myself to sending my AC back for repair.  Hearing that repairs, in some cases took two months to return, it was something that I wasn't looking forward to doing.  I also included my RC unit with a request to tighten a loose antenna, another problem I'd had since my purchase.  DJI had determined that it was probably a faulty sensor and sent a prepaid Fedex label, thankfully.  I say thankfully because I live on the east coast of Canada, quite a distance from L.A. and an expense I didn't want.  The trip to California took six days and the repair began almost immediately.  Surprisingly, two days later, I received notice that the repair had been done and was being shipped that same day.  Incredible, I thought, so many people had posted about long delays and here mine was repaired in three days!  Six days later, on Monday it arrived.  A few days earlier, I had read a review that someone had posted on this forum about the fast and positive experience they had.  I thought to myself that I would also write about the fast service that I had.  I opened the box, looking for some paperwork that might have told me what had been done to rectify the problem.  There was nothing.  I did find that the camera had been replaced after checking the serial number.  Anxious to fire it up, l went to retrieve my iPad.  I took the bird out of the case and then to my horror discovered that the RC was missing.  It felt like a punch to the gut!  I called DJI and when i explained what happened she was very matter of fact "oh you'll have to respond to an email I'll send you and they'll send you the part".  The part?.  My RC worked flawlessly with the inspire and my fear is that they'll send a refurbished RC and I'll be dealing with someone else's problem.  Now, three days after I informed them about it, I called today, only to find that they are closed until Monday for thanksgiving.  This will probably be the last decent weekend weather wise and I'll miss it.  Great!

Thank you for your support . It's the truth that we still have a long way to go .

Hi  Patrick,  just to let you know, I received notice today that they are finally shipping an RC to me. If it isn't my original RC I hope it works as well as mine did.  Thank you for your help regarding my issue.  I can't wait to fly again.
