Previously used Phantom 2, 3Advance. I managed to fly on the Mavic for only half an hour. Wrappers flew off for 1-2 years in difficultcomnditions (rain-snow-wind-strong magnetic interference-permanent flights from powerful radio transmitters for him). Mavic, for no apparent reason (interference, strong wifi noise or the presence of a nearby RES), 100 meters above his head in a clear sky, simply lost satellites andcommunication with the remotecomntrol and went about his business. Of the dealer and DJI agreed that this is normal for the Mavic. Thecompter itself is functional, excellent shots, perfectly follows the object and follows it Indoors, he likes to fly sideways into the wall with all thecomnsequences. When you try to catch him by the belly, he will kick because of the sensors, which can lead to hitting the ceiling (after all, there are no sensors on thecomver) I recommend using spinning when using a drone in open spaces =) Attached photo example.
