Great high quality tool. I expect it to last for a long time.

Not flimsy!, June 20, 2014
Like it because I found that the clip was not flimsy constructed by some of the reviews I read. Works as stated you can see the arc (if looking at tester) as well as hear the arc (if you not looking). Would recommend to friends and family.

Work very well! Very nice tool to have in the tool box. Doesn't require lots of room and very reliable.

Great tester at a great price!, May 17, 2014
What can i say? It does exactly what it says it does. I was able to test all of my ignition wires safely and quickly.

Does its job, March 23, 2014
I have only used it for one job so far, but it works as advertised. The spark is very easy to see and hear even in the sunlight. The part seems very well built and should last awhile. One tip, instead of using the built in clip to ground the Spark Tester, clip a battery jumper cable onto the Spark Tester clip and then ground the battery jumper cable. It gives you a lot more room to work with.

This is a nice spark plug tester to test for spark the right way without frying the coil. A must have!

works just as it should, January 21, 2014
I had one before so knew what to expect. This is a handy little tool that any tech shouldn't be without.

Top of the line tester for the money. All my friends are in line to use it.
Found the miss I was looking for.

easy to use, November 2, 2013
easy to use and works great. Just unplug a spark plug wire, snap onto tester, and clip tester to metal to ground it. Crank engine and watch it spark (or not).

it works like its suppose to and gets the job done.
This tester seems much higher quality then the ones ive seen in auto part stores and with this particular model you definitely cant complain with the price
