Morange in-Line Spark Plug Engine Ignition Tester with Carb Carburetor Cleaner Kit, 6-12V Pick Up Coil Armature Diagnostic Detector Tool for Automotive Car Lawnmower Internal External Engine

Was easy to use. I used to check spark on my snow thrower engine and it worked great.

Wires are a little small, plug caps are stiff and loose. The cap ends were too large to secure to plugs and had to be crimped down a little. Once done, they function well and are a good value for the price.

Works perfect. No equivocal results. If the light blinks the ignition coil is working. The include brushes are nice. I wondered at first why they were included. However, most of the time a small engine will not fire is due to a clogged fuel injector. The brushes are fine enough they work perfect.

Worked great however test before using. Make sure all internal contacts are clean and not tarnished. Ordered the pair however one didn't work. I opened it up and cleaned all contact points then it worked great!

So yes.. cheap for reason.the connector is not too tight and because bad contact does not work good.After I pushed with a plier worked well.So not a professional tool, but you can use this if make a good contacts.I would not buy again, but I won't send back.The brushes are perfect!

I liked being able to see the spark, and doing so, I could tell if it was weak or strong. However, my only dislike was that the wire is a tad short for testing the spark on my chainsaw, but I was able to make it work.

They’re all made in China, regardless of whom is listed as the manufacturer.

This item works great and is handy to know if you have a spark, that way you know the problem isn't a spark and can look elsewhere. The light is also bright enough to see, even with my failing eyesight, Great Product!
