You can

The description of this system at the website is not very
transparent. Perhaps it is the presentation that is making it seem
complicated, but it is hard to tell how this system works.

If it cannot be described in a simpler way I'm afraid that the public
would reject it even if it does all that it claims.

Just my $0.02
