We bought the DVD player for our Children 7 years old and 18 months old, so as not to get bored in the car on long trips. We opted for the device, as it has everything you need there and the two players can be used separately from one another. Who ordered this device does not need anything to buy in addition to cables. The only thing we still order us, are the mountings for the head restraints. Although the enclosed strap are not bad, but press in the foam. In a previous review we had read that the equipment would be much too low, we can not confirm. We had set at the beginning of volume 20 and our kids thought it would be too loud. The volume can be set only up to 14 and to confirm a warning message "Excessive volume can damage your hearing" you can adjust even louder. We find good value for very good.
