“I'll tell you the results first for a busy person. Buy FLY12.
I've been using gopro8 until recently. Once i ride, I even carried 4 extra batteries and an powerbank just in case, and there was a hassle of having to erase the video every time. The video quality is definitely good with gopro. But if you consider the overall things (convenience, weight, playtime...), buy fly12 now. If you spend too much time worrying, you're the only one who loses your safety.”
