Saw it demo'd at a forestry show a few years ago. Works as advertised and cuts surprisingly fast but slower than regular chain. The stones are expensive and since they cannot be dressed they dont last long,  Chains are of course specific and seems to me the bar is also?  In my opinion It's not an every day or even a moderate use system, was designed for homeowner saws used a couple hours a year.
