After my Trekstor after less than two years ago gave up the ghost, I got into a contribution of a defective and replacement unit back, I was a bit sour.
I was really excited when I first 2 weeks after re-send an e-mail was that they could repair the player nor exchange, and offering me a credit for the time value.

As you can imagine, the value of MP3 players after two years is not particularly high. However, it was so nice mp3-player.de, and has yet to put a few bucks and now I get a Cowon iAudio 7 in black and red. If any hurry DHL is even tomorrow.)

So then the Trekstor odyssey is finally over. After 1 and a total of three defective iBeat organix vibez broken within 2 years, I can only advise from this manufacturer. But you get mp3 player.de again the highest score for customer convenience.
I just hope that with the Cowon is better now and I no longer share the player must, at least not before the warranty expired for good.
