I find this kind of media ok. He is super fast. In less than 1 second, my computer has found new hardware. (XP of course) .The transfer rate from your PC to the pin and vice versa is just sensational. But I had finally decided for him because of the eyelet for the keyring because I wanted to have with me a USB key always. However, I had him just a few weeks on a key chain and unfortunately had to find that he has gotten some scratches, but that alone really bothers me little. BUT: The eyelet for key ring broke down in a strange way. So that I can no longer carry on a key chain him. Not just beautiful. That said, I am very satisfied. For all without need a USB flash drive to drag all day around with them, he is a very good solution.
