The sound wafer is a handy little speakers, one can take with you wherever you go. He has a long term - is running at us with no trouble finding a day through. The Blootothverbindung by mobile phone (Samsung Galaxy S3Mini) works fine in a Windows laptop, there is noise (but is probably more on the computer). The sound is better or worse depending on the location, are very good discs. For windows you should note that the music is just as good to hear both indoors and outdoors. The suction cup is a bit tricky to screw, the thread is not completely clean. If he screwed it holds the wafer but sound very good on glass panes.
