The test pen can be used for spark plug test, high voltage wire test and ignition coil test, suitable for ignition system and circuit breaker
Received my Grandi ignition tester a bit late due to shipping, and the box was slightly crushed. But the tester itself works well. I love how easy it is to use for checking spark plugs.

Reliable tool for diagnosing issues
I've been using the Grandi spark plug tester for my car's ignition system, and it works like a charm. The high-pressure cylinder line is durable, and the readings are accurate. Definitely a good investment if you're into DIY car repairs.

Good for the price, but needs improvement
This ignition coil test pen by Grandi is decent, but I had some trouble with the high-voltage readings. Sometimes it felt like the connection wasn't solid. Still, it helped me pinpoint a couple of issues, so it’s not a total loss.
