- Go during battery replacement date and time lost (have to be re-adjusted, that is simply no longer appropriate). - Adapting to changing light conditions takes place rather abruptly and not fluent. - The image of the video is as sharp and clear, but in low detail areas such as skies and smooth asphalt are quite clearly visible block artifacts (excessive compression (about 15 Mbit / sec), 25-30 Mbit / sec would be appropriate.). - In backlight the image with HDR is just too dark. - The Auto. White balance is not very accurate. - As soon as it is no longer day-light, the image quality drops dramatically (just a fair-weather camera). Given the price still a good choice, the GoPro is better but for me just too expensive.
