Yeah, does what it was made to do I guess. It sparks... not very good, but it does. I fried it by plugging it into a variable voltage power supply and cranked the voltage to high heaven because more powa = brighter sparks... nope... shows how much I know about electronics.

Works perfect. I had about 24 Spark Plugs that I had used for different Racing Applications and I wanted to test if they were still good. I tested standard and Iridium's and both worked good. Very handy to have. It won't work on shorter plugs like the kind You use in Weed Eater.

3 out of the 4 spark plugs in my old tractor were bad. Saved me a bunch from ordering a tune up kit, plug wires and chasing a short that doesn't exist.Easy to use. Good value!

This works fine on the Automotive (longer) plugs, but if you need to check the smaller plugs for Blowers, Chainsaw, Weed Wackers, etc. Those plugs are too short to reach the connector inside the box.

I work on small engines as a hobby and came across this tool. I’ve tried it out and really like it. It will come in handy to rule out bad spark plugs!
