Conclusion: Three stars because it costs a lot of effort and patience to wait until the PC recognizes the adapter. (My laptop is from 2012, and up to date)
I use the part for a Brüllwürfel (mini music station with mp3 player). Since one of his songs like in between changes and the cube used more often, the adapter for such a use is not appropriate. The wait until the adapter identification (15min) is simply too annoying ....
