Der Stick wird im Radio in Lichtgeschwindigkeit eingelesen und die Leserate ist offensichtlich auch kein Problem, eine MP3 braucht ja auch nicht viel.Der Stick werkelt nun vernügt vor sich hin, das Lichtlein darauf leuchtet nur kurz beim einlesen und ist auch sonst so unauffäumllig, dass es nicht stört.Ich kann ihn empfehlen und würde ihn zu diesem Zweck wieder kaufen, schon allein aufgrund des Preises.

Good price-value ratio.
Excellent postal service: ordered on 03 Oct, received on 20 Oct, well done NL Post!
An English version of "Instruction of use" would help a lot when it comes to set the gadget.
