I have a large RV/bus and I really need 4 high quality cameras to keep an eye on my back and side while driving. For me, that's a lot more than 4 rear cameras. The screen is big and bright and seems to be of pretty good quality at the moment. My unit was professionally installed after it got caught on a long cable. The field of view is large enough to see both the left and right lanes behind our car.
