Ethos
Sold me their product with a gaurentee of a full refund. Product is useless. They did not refund

I purchased the product Ethos for both of my automobiles. Both vehicles have Driver Information Centers. I followed every instruction to the letter regarding the use of Ethos. After teting for 30 days there was absolutly no change in the gas mileage for either automobile.

I notified Ethos that their product was useless. They sent me a report to fill out. I sent it over a month ago and still have not received my refund.
