First of all, all umlauts are slipped in menus and in the contents a few pixels down what looks very unprofessional. Then we copied several albums on it. On the first attempt everything was deleted and only by reformatting we could ever resurrect the unit to live and something to copy it. The next time (even with a second device) some artists and albums were simply abandoned after the 12th letter. But some of the pieces was stored with the full album names, and shortened part. The ID tags were before copying all in order.
I have both devices sent back.
