Did your driving habits change in any way? I ask because I saw a 2 mpg increase just from changing how I drive.

I remember seeing this and I dont remember where, but someone said it was a farce... I think it was on our local news where they test new products and they said they did not see any improvement in fuel efficiency.

How can you not laugh at this. Not only does it scream scam all over the place, but there is no logic to it whatsoever. Balancing the stream of elctricity? How is that suppoesed to change gas mileage even if it did such a thing? This is just plain silly.

It's at Best Buy for about $60. It plugs into your cigarette lighter to regulate the electrical current.
Total BS.

If these worked, every car manufacturer would be installing them. Shoot, $50 to get your Camry to jump from 30 mpg to 35 mpg would be a no-brainer.

When you actually see the thing the claims are even funnier. This is an obvious cheapo gizmo. It may have nothing more in it than an LED that comes on when plugged into a lighter. Sometimes I wish that I was scummy enough to sell something like this, the people who make it are probably getting rich. Sometimes having a conscious stinks.

And you did your first and only post just to tell us this? And I am sure you have no connection to this product.

Adverstisment warning!!! Yes vendors do review forums and give there, ahem, "unsolicited user reviews". Yes it was reviewed in CU and found to be totally worthless.

I would think if a car has unstable electricity we'd see it in the onboard computers and other flaky power issues.

Scam all the way......
