Title: Worth having, but it is very sensitive to warm temperatures.
Review: ScanGauge II Ultra Compact 3-in-1 Automotive Computer with Customizable Real-Time Fuel Economy Digital GaugesHave been using for 15 months and use it on 2 vehicles a V8 Ford Expedition and a Honda Accord 4Cyl. Primarily use it on the Ford. Has made my foot much lighter on the throttle. We live on the prairies and often have nice breezes. Even a 15 MPH breeze can reduce MPG by 3 MPG. My only beef is that the unit is very sensitive to warm temperatures. I have to continually move it to a shady place or the screen will blank out. Some time the blank out is so severe that it looses stored information. The unit produces a lot of heat itself so heat from the sun trips it to a blank screen. The unit should have a large heat sink to dissipate heat. Over all I would not be with out it.
