Once my Trekstor Organix iBeat had been adopted at 3 months, I was not really a Trekstor buy more product. But the offer for the vibez 8GB was just too good so I knocked.

And Zack! That part is not rushing to the more technical among you for the SNR -> 0 So contact the Trekstor support sought and received the standard answer "... We can not exclude that, unfortunately, their unit is defective ..." then returned to the dealer.
Today it is now time to just four days, a new vibez eingetrudelt with me and what can I say? Well finally the signal to noise ratio in the technical data is given for Trekstor, reached at least subjectively.

My conclusion:
mp3 player.de respect went so fast for a long time no longer exchange.
Trekstor : Give more time for QA finally out. Can not really be that it is a matter of luck whether a device is operating or Nich.
