So much easier (and safer) to then connecting a lead, and watching under the hood for spark! Works on a variety of plugs and has given me spot on results.

This surprisingly works well. Not bad for the price

Chances are, if you're testing spark plugs you have extra fuel somewhere nearby. Whether it's in the dead cylinder, or on the engine, testing a plug by resting it on the block and cranking the motor is a recipe for disaster. This tester works well and allows you to remove the ignition source from the fuel.

My husband always wanted something to check spark plugs. This is easy to use and lets you know when they are weak or bad. It is made nicely. Also it is compact and well worth the money.
