Have my GoPro for a month now and film both concert and when driving a quad bike and tractor. Incredibly good 1080p image and sound at goa 60fps, resulting in a much more beautiful and faster image! Highly recommends for concerts!
When it comes to filming with tractors and quads, I'm somewhat dissatisfied with the focus. It's easy to focus on the darkest parts, making the light of heaven take over the whole. Should you shoot outdoors I recommend cloudy days.
Very easy to handle and film with and even better with the app!
Total score: 7/10
