The picture quality and installation is very satisfactory. The supplied headphones we did not use but worried commercially kids headphones. Here, the sound and the volume is ok. I think even almost too loud. We need to reduce the volume always hard for us to the children's films do not have to listen in at the front.
Until now we had no problems with the playing DVD's. They were all originals and easily playable. Our Great even manages with the remote control to edit almost alone the unit.
I see a need for improvement in the missing battery. It would be nice. if the player / screens continue to run even when the engine is off.
The currently most exhausting for us problem: Willmann persuade the 2nd unit to display the same movie as device 2, this can be not set permanently once. Always at restart of the two players you have here in this 2 player menu awkward as I find set. For a stop or a rest, where the engine is stopped, this must be set on 2 player again when you restart. Here would be at least an integrated battery helpful. Or a permanent setting that can be changed when needed.
Nevertheless, I find Here the price-performance ratio.
