I had repair service made DJI. UPS lost it and all hell break loose. I want to discussion about so that you know in advance what you get form DJI service. In short, their customer service SUCKS BIG TIME. The worst! Don't expect it to be like target, apple, gap, or any american company. Remember it's head quarter is in China. Why am I saying that? 1. DJI, did not take initiative to call UPS to report lost product. I spend 5+ hours waiting on the phone. 2. Turn arround time is always 15+ days still counting. 3. When the product is lost, it's their reponsibility to report the lost. If it were target, amazon, apple, or newegg, costco. They would just send me a new one already and they'll take care of UPS behind the scene for us. BUT DJI, you need to a. file a claim b. wait for UPS to send them the money c. then they send you the replacement 4. Their live chat / tech support is so crappy. I feel almost as if they don't speak english. When I said I want to cancel an order number their naming convention is wacky. 5. Their name convention for product is so crappy and inconsistent. If you have a phantom 3 pro, would you what the difference is between a Phantom 3 Pro vs a Phantom 3 4K. Probably not, and did you know the replacement parts are even more confusing. Here's Phantom 3 Pro - Buy Phantom 3 - Remote Controller (Pro/Adv) | DJI Store Here's Phantom 3 4K - Buy Phantom 3 4K - Remote Controller | DJI Store Why is it that Phantom 3 Pro doesn't have a mobile device holder and phantom 3 4k does. If you buy a Phantom 3 Pro, the mobile device holder is attached with RC as if it's one unit. Also DJI charge me $20 for a $235 wrong order I made.
