I have been using the camera for a very long time (I have never ated the firmware), before that it was goupro3 (drowned), the SJCAM picture is brighter, juicier, a little (just a little bit) bluish. Considering the price, I like this camera more, especially since there are a lot of accessories at once. Gouproshnye are also suitable (except for boxing). When shooting in sunny weather, there is no difference with the gopro. The battery is kept the same. To work in the premiere, you need to install the utility, because by default it does not see files from the camera (but it sees it from gopro). SJCAM went under a truck on the track, bought SJCAM M20. Upset. In addition to the remote control, it has no advantages compared to SJCAM 4000wi-fi, but it costs three times more =(
