I bought this USB flash drive because I was looking for a small and unobtrusive USB stick for my car radio. For that he is well suited, since it provides a lot of memory at a very small size. As USB flash drive for data transfer to and fro, I would not use it because it is simply too small and therefore can quickly disappear. As an extension for a car radio, he is super useful, since it is hardly sichbar and the red LED does not bother.
