Alligator clip fell apart first time I used it, cheaply made.

Well made product, was chosen to replace the cheap plastic spark testers being sold. Vehicle manufactures are recommending not to use the plastic made sparker testers as it can cause voltage spikes and short coil packs.

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.
