I was initially surprised by the price of less than one euro while supposedly similar products sometimes cost up to 10 euros. I figured at 99 cents, you can not go wrong and the file I've bought. Downloading worked flawlessly and playback in MP3 Player (VLC) made no problems. But then off we went: the file could not be copied to the Explorer, to move or rename and convert popular MP3 editors (eg Audacity) could not load the file because of "incorrect file format". Magix video and audio programs could also not process the file - but just that I had bought. What struck me: the extremely long file name including German special characters.. So I wanted to rename the file, but as mentioned the Explorer does not offer this option in the file. Ultimately, I then can perform the good old Rename command at the DOS level and have awarded a "normal" file name. Lo and behold, now the Explorer was working correctly again and also use in the other programs worked finally. Now I could see that the volume of the start steadily getting quieter until the end of more than an hour to complete silence. That's not natural and so unacceptable. For all these reasons, I can unfortunately only awarded one star.
