The reason they look so pretty is the ability to scattter light rather than to reflect it. A real mirror (flat surface) will send the light in the desired direction.
Also, the CD size is not ideal for single hand holding. Remember the mirror goes in one hand and the other hand is used as a sighting device to ensure that the light is directly on your target. This allows the signal to be sent either in flashes or a steady beam. This is handy to distinguish a distant signal in the forest, for example. Or signaling a helo or plane from the sparkling surface of the ocean...
I am not the only one out there making signal mirrors that are suitable for diving. If you want to be seen, get a good quality signal device. You can easily find alternative brands over the internet, for example. The best ones for diving are the ones that have a sighting hole rather than "clear spot" or "Halo Spot"
Just things to keep in mind.
