Since the write speed is only about 4 to 5 MB / sec (1 star deduction), this connection is certainly not suitable as a constant companion constantly changing to transport data. But for car radios etc. it's great. Once recorded with a neat selection you really enough music for months there! ;-) Due to the small size of these really stick falls not on the radio and mechanical damage by catching on long protruding parts is not possible!
