After some back and forth I decided Unwrapped for Pio 170, connected and tried several BDs. No matter what disc I fed him, I had every time a high-frequency hum of the drive that despite Filmton in about 3 m distance was still audible to me. That was me already equal to the pointer, so I packed up the player again and decided for a return. The humming died away with every chapter jump. But the first half an hour is not enjoyable for me.
Another issue is that the picture and sound of the player are properly. No complaints.
For a player, the distinctively sets itself apart from the Billigheimern for 40 to 60 euros, I just expect better quality. Since not only the name of the manufacturer should make the difference. So I was a bit disappointed.
