Very quickly discharged, especially if you forget it in the cassette player! After turning it off, it's the first piece of music that is on the card which will be played again at the next use ..... What makes you always listen to the same music .... Of course there is the remote control to zap but it no longer works after two days (longer battery!) The car charger undergoes false contacts, earphones I do not even speak .... In short, a Council, go your way and prefer a K7 adapter with a 3.5 mm jack output and plug it an mp3 player or smartphone, you'll have a much better result that this evil manufactured toy!
