I use these small USB drives for promotional use for distribution of my original music.They work and for the price I can afford to give away these USB drives to fans, promoters and radio stations for airplay.* Definitely an easier medium to carry around with you than bulky CD’s, etc.* Much easier to load these drives up with my music samples than burning CD’s and much faster to copy files to them than CD’s as well.* A unique and modern way to promote and distribute music. People real like that they are receiving fancier and a Tech like product rather than a bulky CD. An excellent touch and tool for promotional / marketing usage.* For use as a music sampler for giveaways, etc - I use the 128mb version USB flash drives. I am able to put 10 + 320mbs / MP3’s on them with some room to spare.* people really and are excited when they receive my music in this form.They won’t need to convert any audio files or burn CDs via their computers, that’s already done for them.* Works with many different devices such as stereos with USB ports, Smart TV’s and DVD players, a majority of modern vehicles that have USB ports as do not come with CD players. ( I am seeing more of these audio system configurations on new vehicles than before ) (Note: Some car mp3 players can not read the mp3 files when they are in folders on the USB flash drive, so don't use folders when uploading mp3 file on to it )* A decent product and great price..Recommended!
