Have bought two devices to the children entertained while driving. The sound is just fine, the operation. The range of functions is limited. Connect to PC worked perfectly under Windows XP and Linux. The dubbing of the files is very slow. Of the promised USB 2 I have not noticed. Dub 2GB data takes about 1 hour. The unit does not provide the possibility of sorting. If you want to play audiobooks in the right order, you have to play the files in the correct order. The player plays the files only in the stored on the FAT order. For the price I can see over the rickety housing. The slow connection and very limited utility for audio books are my only worth 3 stars.
