Does what it says on the tin. Not given it 5 stars as the connection could be better between adapter and iphone. This could be due to protective case I have which comes up close to port for charging..
A friend recommended this product to allow me to use my new iPod Touch with both an older iPod stereo dock and iPod iTrip car radio device. It saved me at least £150 from buying new devices for the car and stereo. It is an excellent little device.
Does exactly what it says on the tin doing exactly what I need it to do.
