Great gadget, every car should have one!
Installation is just a plug away no messy wiring to deal with. Size is small and compact not bulky like other gauges, no need for other gauges anyways you have a multifunctional gauge all in one. Price of the ScanGauge is affordable at $170 or even cheaper with coupons from the site. I recommend the ScanGauge OBD II. It takes only seconds to install, and can save you a lot of money either through gas savings, checking trouble codes, or spotting potential problems before they turn serious. This is a must-have for the car enthusiasts. I originally bought them just for the voltage since my car didn%X92t come with one. The gas savings is just an added benefit and soon the gauges will pay for themselves with gas on the rise again.
