Bought mainly for the motocross sport, the helmet camera. However, I have also often made motorcycle tours with them. The image quality is unbeatable for me in this price range. It makes comparison white same video as the GoPro series. Moreover, it is waterproof without any additional housing. The only thing you can complain about is the image radius which, however, is also not bad. (The GoPro have a greater wide-angle)
+ Image quality + Waterproof + Long battery life + Price / performance unbeatable
-At Night the image is out of focus
Wants to spend on each of the no 300 for an Action Cam is the ideal solution.
