has any one tried the tornado fuel saver? if so is it worth the $70. really looking to inprove mpg . any other ideas how to?

IF THE THING WORKS, and it cost $70.00. How long would it have to work for you to save $70.00 in gas?
I have never heard of anyone of the "fuel savers" that work. But I'm sure someone will tell you that it will. Good luck
