To operate:
1. I also note a much too low maximum volume. Somewhere I had read, that was the derated due to EU regulations and this restriction can be set by entering a non-EU country out of service, but find only language setting in the SETUP menu. It's please each own responsibility for his listening habits and their health.
2. The display and the displays are relatively pleasant, but the resolution (and thus the sharpness) of the screen - well - technical level of 5 years ago. I'm sure a decent screen resolution would have made the device not much more expensive.
3. Even something positive: After copying the MP3 files (over 500) were created automatically indexes all the MUSIC directory, so play by album / artist / genre, etc. was possible immediately.
All in all, after the first spontaneous acquaintance 3 stars.
