great item works awesome wish i got it sooner

Only used this twice and the light bulb burned out. It can't be used now.

Works like a champ Just need to put whatever you’re checking out of bright light. Easy to use. Great quality. It’s a keeper.

This item helped me diagnose a rough running V-twin lawn tractor engine. I had already replaced the fuel system components and the spark plugs. I neighbor backyard mechanic suggested I check the spark plugs for spark by removing them and grounding them and examining the spark. That sounded undesirable to me, so I found this item. It is simple to use, just install it inline between the spark plug wire and the spark plug. It clearly showed me which cylinder was misfiring, and an easy coil change fixed the issue. It is a great item every engine home mechanic should have! The quality is very good and the price under $10 makes this a bargain. Highly recommended!

Easy to see "spark" in daylight. Nice bright bulb.

This spark tester worked perfectly

This tool only works on spark plugs that have the" nipple" if the spark plug just has the threaded end like many small engine plugs, do, you cannot use it on that type. It seems to me a huge oversight.

Does the trick! Can now test my spark plugs to make certain they are functioning as the should.

I used the product for the purpose it is designed for and it works very well however it is a little flimsy so care has to be taken when handling and storeing this tool.

判断しやすいです… 大きさもちょうど良いです

Works well, connects easily, would be nicer if the cable was longer as it can be a bit difficult to hook up in certain spots

works ok
