Do yourself a huge favor and DO NOT buy a drone from DJI. You will regret it if you ever have to involve customer service. FACT - my Phantom 4 worked fine until I had to download the DJI GO4 app. There was an immediate problem and the drone and controller were clearly having communication issues. Others have had the very same problem. DJI, incredibly, denies this, "If it's the software that caused this, then all of the Phantom 4 user experienced the same." They said that AFTER they said this - "We understand that the problem seems to start after the new app has been downloaded", so the fact is they will lie to you. Or at least some of them will. The honest comment came from a first level customer service rep in November, the dishonest comment came from Francis, a technical supervisor in February. Three+ months and 30+ emails (all kept to substantiate) and they still think I should pay $438.30 (hey, discounted 10% from the original $487!) to fix it. They claim a hard landing (it's their go-to response to stick the blame on the customer) caused THE BOARD IN THE CONTROLLER TO FAIL!! They've sent responses that imply it was the first time I contacted them. They ignore specific questions and information and just stick to their script. They came back to me a few times about the warranty being out of date. It's not a warranty issue, I never mentioned warranty, why are we (again) talking about warranty? We're talking about your app disabling my drone and then nothing being done about it! After their most recent response saying I can pay or they will just send it back, I said send it back. I intend to make a video while I blow the thing apart. My guess is that a prospective DJI customer watching an actual DJI customer blow up a $1500 drone will send that buyer elsewhere. After telling supervisor Francis that this was what I intended to do, "We apologize for the inconvenience." is what was offered up. An inconvenience??? That's what they call it when they disable a $1500 customer drone and refuse to fix it! While I'm out $1500 it is my hope that this review will save countless others the agony of dealing with dishonest DJI and will ultimately cost DJI far more than $438.30 in lost sales and margin. They truly deserve it. Do not make the same mistake I did - DJI has a lousy track record, it's well documented now. There are far better options out there. Worst customer service experience of my life. Don't let it happen to you, don't be the next victim.
