The stick was purchased for a TP-Link router to a small network storage and FTP server to run over it. The stick is of course not the fastest, but operated on the router it anyway limited elsewhere. I think also for car radios or kitchen radio this stick is very well suited, because in order to play MP3 files from it I do not need high data rates. As a stick for the keychain but only conditionally suitable as just very slowly and the cap also does not sit firmly insane!
5 stars because good price with small size, to the reliability of course I can not say anything yet.
