Drone is well built and quieter than other drones I have flown. Flight time is outstanding. The camera does not do video well. I have tried two different micro sd cards, one capable of 170mb/sec speeds and the video will start jumping them smooth out, jump some, smooth out, over and over again. The gimble does great at keeping the image stable but the video quality is not usable because of the skipping frames. The return to home is accurate and the image track works well. So does GPS track. If you are in an area with poor GPS signal. The drone will all of the sudden just take off. Unfortunately my house seems to be in one of those areas. All in all it is a very good flying drone. The 4k pictures are good but if you are wanting it for video, mine anyway does not do that very well.Update:The video is fine that was recorded on the phone. Looks like the choppy playback is due to my computer hardware trying to process the 4K video. My monitor is not 4K. With a full 4K set up it should be fine. Do check the GPS signal where you fly though. It fly's excellent with a good signal but is there are any obstructions like buildings around the signal will degrade and you can have flight stability issues.
