So many SCAM adverts - I have tirelessly complained to the site publishers about the repetitious SCAM Bitcoin adverts........
If the advert Dick is seeing that purports to reduce a car's fuel consumption by 15% to 30% is the "Ecodrive" or the even more fabulous (but identical) "Ecobox" claiming fuel savings of 35% to 40%, read this review before you lash out and buy:

Like the advert, the product is a phony SCAM.
It is embarrassing that PPRuNe hosts these SCAM, fake and totally misleading adverts.
