This thing actually works. And it work very well, It works as advertized.
I am in not way related to the company selling it nor to any of their employees.
I don't know their marketing agency and I receive no commission, or bonus of any kind for my very positive comments.
As this product is so effective, I installed four (4) in series on my car.
It saves 27% of fuel for each. And the saving is cumulative.My actual total saving is then 108% of my consumption. I now have to stop to my local service station to empty my tank on a regular basis.
Great gadget.
