Title: Good for quick tests
Review: This tool helps diagnose ignition faults in older vehicles. It gets placed on the spark plug wire and lights up with the spark. It's basically a spark tester, but works on the wire instead of the plug. It does work, when it can be used. The problem is that you'd be hard pressed to find a vehicle it will be useful on. Unless you are working on project cars, this tool will be sitting in your toolbox for quite some time. That's nothing wrong with the tool itself, it's just that technology advances at a rapid pace.
