Could be improved. There were no instructions included with the product. Got it working, but still not sure of all the features and what each button does. Probably on line, but I haven't had time to look. The mounting adhesive was not good enough to hold cam mount to the glass. Had to go out and purchase mounting tape. Removing the camera and reinstalling to the mount is a little difficult. The rear camera comes with a long connector wire, but I decided I didn't want the wire hanging from front to back so I'm not using the rear camera. It would be nice if the unit included two mounts so I could switch the camera from one vehicle to another.
