I bought a set of 5 thinking they would be great for carrying different media files. I've only used two of these so far and both started deleting my WMA music files when I left USB sticks in my truck. One of the USB sticks recognizes about 1/3 of the files after a few months of use; the other is slightly better but has been used much less frequently. They might be reliable if kept indoors only, but I wouldn't trust any of the important files on these drives.
