I was really surprised by how easy this was to set up. You literally just plug it in to the car charger and it will automatically turn on and off when you start or stop the engine. The previous one I had needed to be directly connected to the battery and even after I still had to configure a few things.
Haven't gotten into any accidents yet but do have a few clips of idiots on the roads. It fits perfectly behind the central rear view mirror on the windscreen so I don't even notice it while driving. The wide angle means it has a good view of the road at all times.
The footage runs on a 1 to 5 minute loop, so you can easily find the footage you need from a week ago just by the date and time on the video file. It auto erases the oldest file once the memory is full so you never have to worry about changing out the memory card or deleting files for more memory.
The 1080p camera means you can clearly make out anything on the screen. And the easily removable memory card means you can quickly transfer any files you need.
