My choice fell on this device here. For not even 30EUR it was cheap and the existing ratings could be made neither defects nor excessive noise. And also the "mistake" that Polish is preset instead of English or even better German was described as quickly remedied.
Now my impressions ...
The unit came in a religious union and packaging is different, not cheap by (if you like the design) Connecting to the existing TV set went without problems of Equip, because the label on the back is easy to understand these types of equipment.
It was followed by a function test and an attempt to change the system language in German. For second option my experiences.
Only menu> then Setup> top riders> yazik> German. (The language was not a unique way to make the selection, but only after about half an hour in operation.)
Summary
+ Play many formats
+ USB
+ S / PDIF
+ German menu
+ Remote control with batteries
- Polish preset (switch to German with obstacles)
- Limited, partly bad understand menu
- Rather stale menu (almost equal to 9 year old "predecessor" of Xoro)
- Instructions incomplete (Polish / English)
Despite the above points I would the unit lack meaningful alternatives to 30 - 40EUR buy again.
