As a busy dad, I worked hard and tested it in a week at Uber. Mileage increased from 40 to about 54 per gallon. All I can say is that it really worked and I never expected that..
Very cool invention! however, I believe that this technology should be made public and offered for free! I only paid $27.99 and not more so I'm glad. It's worth it.
Received in good shape and it works. Nothing to complain about, awesome find!
I tested it and got a ~ 20% higher MPG. I wanted more, but it's not bad.
Bought 2 pcs, gonna use them on my Chevy trucks.
After buying the first one last month for my truck, I took another one for my gasoline car. worked great for me
got a 15% higher gas mileage on a 3.2 v6 with this. Not Bad, thanks a lot Thetechdose!
