I have used both Champion and this brand in the past. Both work well. I really like being able to test two plugs at the same time. I also do a lot of work on experimental aircraft. Having the additional adapters for different plugs is very nice. The auto clean adapter is mostly useless. It does work for some plugs, but for the hassle it’s not worth it. If it was an option I would definitely not purchase it. Other than that. This is a great product.

I like this unit, I have always used the Champion one at my Sons business and I think this one does the same job. If can make two comments, one is the air fitting, it is not very accessible or easy to change. Second it does not seem to have the same spark power as the Champion. It may just be me, I can not compare them side to side.

The only way to clean and test plugs. I've used one in my shop for 30 years.

I used 2 of these exact models and both of them are great for testing spark. Only problem is the fact that the cleaner doesnt work very effectively and compared to the SPARK PLUG CLEANER 2-WAY BLAST OR AIR P# 12-01684 it is very weak. Old shop bought one new and this new shop just got one and its not impressive to clean plugs just test.
