First long-haul experience with 2 children

So, we came back from the holidays in Italy yesterday and had in advance of this system bought to have on the approximately 2x 1,000km "peace" in the car. And what can I say, has worked.

The system runs properly, the quality is very good. The digitized DVDs of children who can easily play on stick with 32GB. DVD also works without hesitation. SD card I have not tested.

What positive notice about the device:
Connection and operation without any problems and intuitively
Picture quality is very good
the size of the monitors has 9 "excellent
The integrated battery allows the film continue even when the car is stationary or at a short stop, the film can be set to pause and be seen

What could be improved:
Remote control only works at close range and not from each side
the straps are catastrophic

What comments there:
the image on the 2nd monitor is slightly worse, but not serious
make absolutely sure that the plugs are all right in there, otherwise there is diagonal stripes on the 2nd monitor
against a few euros more a sensible bag for storage would be great
