The first unit went back because a thick scratches on the screen and the original packaging was opened. Apparently one returns. Device "number two" was indeed then optically perfect, unfortunately allowed after each USB flash drive MP3 mode (with various sticks) then the radio no longer start. Initially went through battery removal (which unfortunately the time and all the radio stations put out), then even that did not help more. Not recommendable!
The return from Amazon worked quickly and well.
