I'm Danish and suck at writing German, so I have to write in English.
I hope you can understand what I'm writing.
In my opinnion this product is first class. The audio/video lock feature ensures that Audio and Video is always in synch, which is very nice. Picture quality is excellent, so is audio.
I can only recommend this product.
I Denmark it is quite expensive, however I found it to be more than 150€ cheaper here in Germany :-)
