Review on π₯ JND Premium Ignition Spark Tester: The Fool-Proof Engine Diagnostic Tool by Joshua Mejia
Poor quality, best spark plug thread repair kits
The light is very weak, you need to use it in the dark, forget to use it in the sun. The connector that should snap onto the spark plug won't snap, is flimsy and not well made. Even after crimping it harder, I could barely make a connection with the connector. The whole block feels cheap and light; For the price I wouldn't complain that it's only flimsy, but this product barely works. A return is also not possible! So one star for a one star product from a one star seller.
- A must-have diagnostic tool for any engine with a spark plug
- A doubtful purchase for the elderly
