First of all I wish to indicate that customer service is impeccable, indeed, I received a first camera that had a color problem and after a short email exchange, they sent me one. Concerning dashcam in itself, given the price, I'm happy. It starts when you start the engine and turn off when cut, there is no operation to perform. The quality of the image is correct although it is not able to read the number plate of the vehicle in front. A very nice little Lock button is the button that saves the current sequence so that it is not crushed because the camera works on the system of perpetual memory by re writing about the beginning when the card files is full.
