because I go in for many extreme sports (for example, I ride different bikes, horses, scuba dive, and also drive cars on a special rally track) but sometimes it is buggy (almost 15 minutes of excellent recording was lost), and when shooting drift it is not felt at all (due to a small "fisheye") it is very convenient to shoot everywhere. With its pros: excellent video quality, quite tolerable control via smartphone With its cons: sometimes dull, there is a strong lack of matrix stabilization, in some cases it shoots badly
