doesn't work, don't buy

The first thing bad about this item is it's not even shipped from th USA, i had to wait on it from china, which took forever to receive, 2nd bad thing about this item, it says plug into cigarette lighter and it will improve gas mileage, I plugged it in and seems like it used more gas.

Complete fabrication

Installed device, ran three tanks of fuel. Made absolutely no difference whatsoever in my fuel economy. Total waste of time, money and effort. Should've saved money and put it toward fuel.
