Honestly very good article, price / quality ratio. Good image quality, screen size just fine, easily installed, beautiful aesthetics. The screens do not rotate, but there is a function for remote viewing angle change that is a real plus and avoids handling screens. Power cord length cigarette lighter OK Too bad they are not provided headphones. The noise level is a bit limited, but it may be that the manufacturer intends to limit inconvenience to other occupants of the car and encourage customers to buy headphones or earphones .... .... Anyway I recommend this product.
