They were very helpful.
I loved my Phantom 4. It was great until I went to fly this on a afternoon and as soon as I took off, it went crazy. I had no control, and when it finally crashed, it did into the river. I'm a very conscience flier; I never fly unless I am sure it is safe. Contacted DJI customer support, sent all information they asked for and was really impressed with their response and resolution when i got word today that they will replace my aircraft. I can't wait to get my Phantom 4 back and go flying again. DJI came through. They held to every single time commitment they made to me and my new drone showed up yesterday. I was a little nervous flying it at first but it came right back to me. Keep up the awesome customer service, DJI.
