Principled I have been satisfied with the device (4 stars), but I already have to request two replacement units because the MP3 player when used properly (but daily) use after approximately 4-6 months was broken (do not read more switched on). For each of these replacement devices I have deducted a star.
Otherwise, it should be said that in the delivery, the maximum volume to be desired leaves much. But this is by a little trick to fix (region change). Navigating the device is basically okay, but slow when loading a little folder with a large number of files.
