Do not buy DJI Mavic. The gps system in these drones are faulty and sometimes loose the ability to return back to you. I had this same problem on a recent trip to Svalbard and it caused drone to stop being responsive to left right, or front back controls. After 43 minutes, the drone ran out of batteries and crashed into open water and could not be recovered safely. DJI is aware of the problem but still not provide an explanation or a replacement or a refund. Now, their service team won’t reply anymore. I recommend using a third party company for drone purchases until DJI can figure out this error with their products.
