I must say after watching both of the videos above, the second one in particular, where the guy is riding his motorcycle; the following capability and the avoidance especially, are quite amazing. There is a point where he goes under a bridge that is at flight level and the aircraft smoothly avoids it and when he is riding next to, and thru chain link fencing? It sees and avoids it as well as trees, lamp poles and other stuff.
For a following, hands free, no controller, drone - this may be in a class all it's own at that price. But beyond that, there's not much to write home about. The drone is 1,000 bucks but the controller and beacon add 300, and that is with only one battery, so it's not such a great overall deal. However if you need a drone that can follow you thru the woods - this might be the one you need. ? ?
