Has anyone tried FUEL SHOT?

[RunRite]

Just curious if any of you have tried our FUEL SHOT product yet (shown on this week's show #712), and if so, what results have you had?

Would love to get any feedback you'd be willing to share ... it really does a nice job with improving fuel economy.

Thank You.

I saw a lot of rhetoric on the website. How does it work, as I am not even slightly convinced of any benefit that can be had. Nano technology is one of the latest 'buzz words' but that still doesn't define what those little 'nanos' (I say this tongue in cheek) do.
