I have used the FireFly fobs for many years because I liked that the drive detaches from the bottom of the fob and the cap stays on the ring. I didn't like hanging my keys off the drive or handing my keys to someone to put something on my drive. But that far outweighs this option. Obviously, unlike most other modern flash drives, it's not plastic. It works a million times faster than what I had. I didn't think I noticed, but I do. I'm not worried about this key breaking and I need to be careful with it or make sure it stays in place and doesn't come loose from the keychain. Last but not least, it does not draw attention to itself by LOOKING at the flash drive to trick someone into stealing it when it is idle for a few seconds, among several other clues. People steal keys all the time just to get a flash drive. But this one is much more secure because it's silver and it matches all my other silver keys and rings. Most of the time I have to double check to be sure because I don't notice. 12/10 recommend. ;P
