I find quite respectable, and the sound is good for this price range.
But the operation is - shall we say - suboptimal. Very suboptimal. Here's an example
CD playback:
Ok would: after the CD insert press Play.
Here I must after Inserting a CD 6 press buttons (!):
1. Change mode.
2. At the wheel CD.
3. Confirm your selection.
4. Press the menu.
5. At the wheel, select Start.
6. Confirm the selection.
Can you live with, but good usability is something else.
