Negative Positive
Title: Just another gadget
Review: Thought it would be useful but after one day of watching the display bounce around with the numbers, it really isn't very accurate. Even with the cruise control set, the "miles per gallon" jumped around so much, you find yourself watching the gauge instead of the road. The other thing that relly sould be noted is that the voltage showed 11.5 volts indicating possibly a dead battery cell. Since my battery was 3 + years old, I figured it was time for a new battery, thanks gauge. Well, before I took the plunge to buy a new battery, I checked it with my battery load tester and two other volt meters. The result was 13.2 volts on the volt meters and the battery passed the load test just fine. Therefore the ScanGauge II got the AXE (sent back). Most of the info on the gauge is a duplicate of what is already available on the vehicle, and the accuracy is questionable.
Is the review positive or negative?
