The best after sliced bread for video lovers. The stable cam function works perfectly. There's still a bit of up and down movement when you walk with the device, but it's still 1000% better than a standard camcorder or iPhone. I've used it from a standing start and from a moving car and the video was absolutely smooth. 4K video is sharp and clear. The lens doesn't have a lens hood so I wouldn't shoot directly into the sun to avoid flare, but other than that the exposure is great. I would recommend two accessories: a tripod mount and a steering wheel.
