Evaluation by Truckers
We offered some free ECO devices to members of TruckersReport.com, and got 10 volunteers who agreed to install the ECO on their big rig, and report back to the members - good, bad, or otherwise.

We didn't know the guys, and all agreed to provide honest comments. We also have been prohibited from advertising on the forum web site, even though we would like to. They have a policy of not allowing fuel saving devices, since there have been so many rotten ones.

Early results excerpted from TruckersReport.com, in August 2011.

Once we get all the results from all 10, we will summarize the results here.
