I didn't say that. There are fast, fine hard stones but they aren't reasonably priced.

From the video it looks like a nice medium hard pre-polisher. I don't say that to be derogatory as you can get a great edge from that kind of stone , after all people even get great shaves from Norton 8k's, just that if it can remove DMT 1200 scratches quickly it is not as fine as a slower harder polisher.
