Works good to test spark. Was able to track down my problem to incorrect firing order from someone else’s attempted repair.

### ⭐⭐⭐⭐ great design but....
*by D***R on September 6, 2025*

I liked the option of adjusting the gap to check the strength of the spark, and the alligator clamp to get a good ground. The price was right, and the quality was good. My only complaint is that the head that goes into the ignition wire doesn't fit securely. It is removable, and it would have been nice if there were different heads to fit different applications. I will remove some from old spark plugs I have around the shop and see if they will screw onto the tester.
