Edge EZ

582 4
I can possibly get an Edge EZ box for $215. I want to know as much as i can about this product as i can, before i commit to purchasing it. i want to know the pro's and con's. I know it will get me better fuel economy if i drive it the right way, but i dont want to break anything.... any info is welcomed. thanks in advance.
