I have on of these... works fine. Although one improvement IMHO would be connected the floppy via usb instead of the standard mobo floppy connector. As it is, it requires connection to a mobo usb header, psu, and mobo floppy connector. Making it a usb floppy would be nice.
One funny thing I find about mine is that the floppy drive literally shoots the disk out when I press the eject button.
