Yes I have experience with small Mp3 - players and therefore publish a realistic field study hereby! It is to a review every three SanDisc that I had previously. None of them has longer "living" than 24 months, this last here less than a year !!!! The two previous problems with the auxiliary port each had (wobbles, disturbing noises and cancel the far too sensitive solder joints) This player simply gave here on his service and can not power on! Just like that, probably without warning, a defect in the battery. I advise HEREBY EACH off such devices INS to bring home. By that I mean equipment where you can not replace the batteries. So if the battery is over (and those things are extremely short-lived nowadays) then one can to throw away the whole thing. And work goes doubble behind, ultimately, for us consumers who trawl through their songs .... and nothing can be transmitted by a defective MP3 player. ALSO STAND CLEAR, I see myself to a player whose battery you can switch. CustomersLinked Arsche is !!!!! cheap stuff from China, nothing more.
