REVIEW Ipod nano clone 5th gen. 8GB 2.2" MP3 MP4 Player FM Radio Camera

just received my 8g ipod clone 5th generation from Hong Kong (ebay seller: etime2010) 26 euro shipped; it supports Touch button + Shakable function + Camera +Built-in FM Radio; there is very annoying problem: everytime i enter the RADIO and use it a little bit, then the buttons are not answering anymore as they should, there is a sort of LAG, have to press 3 or 4 times the Menu' button, and to avoid it have to restart the player! MP3 quality is not good and battery life is short (no more than 2 or 3 hours). Firmware version is: 090708_V0.3 ATJ209X/ACU75XX VID = 10D6 PID = 1101
