Two things I do not like, otherwise I would give it 5 stars.
The USB connection would be better placed on the right side of the device,
because I have the first USB flash drive already broken while driving.
When you operate incorrectly hingeguckt and already come with his hand against the USB flash drive.
There is also a solution that best ordered you feel the same or a Micro Mini USB drive to
this is just about 2-3mm, and is therefore no longer in the way. I have the same for both the equipment and the respective 9, -EUR invested (for each 16 GB).
The other thing is the files on the USB flash drive. You have these if necessary again resorting (with an extra software).
The files (eg mp3) can not be sorted by numbers or alphabet taken, but as you yourself once pulled the files on the USB flash drive.
The two things are not so disturbing because they (almost) may leave, but could be improved, they are all.
