It is a HHO scam the japanese Genepax company name. Has been hijacked by some scammers using it to marketing something named Water4Gas and Gas4Free. The scam is somehwat more clever than the average scam of this type. How stupid can people be. By the way I ordered two "FuelReducer mpg+" units. Hope they arrive soon so I can cut my fuel by up to 45% wov.
