In principle, a very well-intentioned device if the following serious errors would not occur: With the latest firmware (02.01.86) the unit or the connected hard disk in Windows home network can often not be found. Thus the player in this configuration is unusable for me. After a rollback to the next older firmware this problem can indeed be solved, the player has difficulties but then repeatedly to recognize the direct-connect USB 3.0 hard drive. Disabled Further activation of the media library at me in a very slow perfomance results, can not be used for the storage of favorites. If the issues are addressed by future firmware, I adjust my rating accordingly.
