DO NOT BUY!!!!! This plug-in messed with my vehicle computer making it seem like I still had gas at the time I ran out of gas. My low fuel didn't even come on. I have never ran out of gas. My son and a stranger pushed my off of a very busy road. Didn't even want a refund. I just disposed of all 4 I bought.

I’m not exactly sure that I should have purchased these items. I read more about them and I’m afraid that it might do damage to both of my vehicles. I can’t afford the repairs so I have not used them and I actually gave one to a friend who has an older vehicle. I don’t know if she ever installed it either

Works well for fuel economy to notice the difference. It’s easy to install as well good value for the money.

Just a scam. the only pins that are even soldered to the board is just power and ground, just enough to make the light blink. TOTAL SCAM, GARBAGE!P.S. the only reason I gave it one star, Amazon made me pick one.

We have Toyota Prius C

There is no difference in my fuel economy. But at your own risk

This ECO device puts your vehicle in full time ECO drive. I could never remember to switch my driving mode to ECO on my Ford Explorer. The first road trip with my ECO device netted me up to 35 miles to the gallon. This was unheard of for my vehicle. I have bought 12 of these and distributed to my family and a few friends.
