I do not know anyone here can write, the device is almost illegal strongly. In my not anyway. Ok, battery lasts relatively long, it switches off if no audio signal comes, blue LED is ok, the hardware grabs something "cheap", but I've had worse Chinese goods in hand. The main problem is that the volume cih full and on radio also has to turn up almost the maximum on my device to be able to hear anything at all useful, and with constant noise in the background. Definitely just sidestepped the total bad buy.
