The putty knife is completely matched with the car. It is compact and does not cover the line of sight. It is installed like the original car, but it is not visible that it is installed. The key is that the video is very clear, and the camera can be moved up and down, this is very important, the field of view is very wide. The customer service is also very professional, patient and enthusiastic. I will introduce such a good driving recorder to people in need.
