The gain from something like this is too small to make it worth the money. You start getting 20 mpg then that is something worth it.

We should all pitch in $10 on here and have a few people in one area install it on one members cruiser and document everything with video and pictures. Then everyone can see how good/bad the results are and base their decision on that. I think it is just some people trying to sell you some crap that blows bubbles but that is my opinion.
