"This design is the acme of simplicity. It quickly and easily gives you a ballpark voltage figure with which to evaluate the "health" of your spark. It's probably not a tool that the home mechanic will use every day and there ARE less expensive spark testers on the market (though no cheaper adjustable ones) but it's WELL worth those few extra dollars because you WON'T wind up wishing you had bought a "better" one. I am VERY pleased with this product. [ for questions] Thanks."
