Unnecessary frills and lack of technical details.

Here are the reasons that have led me to return the device:
1. When adjusting the bass boost is also the red light changed.
There is only one setting without illumination in me the sound (Flat) but do not like.
2. When playing from a USB stick I have set Shuffle. I turn the unit off (standby) and
then again, the random play is not selected. This setting is not stored in standby.
3. The display to display the title or the directories is too small or too large font. There are 8 characters felt displayed the rest is scrolled after a short time.
