Wide Application: The inline spark plug tester is a must have diagnostic tool for any engine with a spark plug, it fit for all internal and external combustion engines, cars, trucks, motorcycles, chainsaws, trimmers, snow-blowers, generators engines etc
I had a bit of difficulty getting these spark plug testers to fit my larger engine. They seem to be more suited for smaller engines like lawnmowers. They do work, but I wish the description was clearer about what engines they’re compatible with.

Broke after a couple of uses
I was really disappointed when one of the testers stopped working after using it just twice. I liked the idea of the inline model, but it didn’t hold up for my needs. Hopefully, I just got a faulty one, but I won’t be buying these again.

Reliable spark tester for my lawnmower
I bought this spark plug tester to diagnose issues with my lawnmower, and it worked perfectly! The inline design makes it super easy to use, and I love that it comes in a set of two. This tool has saved me a lot of time and headaches trying to figure out what was wrong with the ignition.

Decent tool but had shipping issues
The spark plug testers are nice and easy to read, but it took longer to arrive than I expected. Once they came, I found that they worked well for my car, so I can't complain too much. Just be ready for a possible wait if you order them.
