The only complaint is the GPS. With the accompanying software that is quick to install and easy to operate, it works very well indeed, but he is among the first few minutes of video, no GPS and can make no statement for locating accordingly.
The GPS speed is not really correct. So I was, for example, flashed in a built-up area. Luckily I had the camera that the speed camera showed me again that I overlooked and the moment when it triggered. According to GPS speed I drove 64 km / h. On the photo Blitzer stood but, in my favor, "only" 58 km / h. So easy 6 km / h difference. I know there is a tolerance deduction of 3 km / h. ;)
But that's about all I have to criticize. From the camera and image functionality I am overwhelmed as I said. And can only recommend this product again.
