Most compression gauges have the Shrader valve located in the gauge itself. This causes an extremely inaccurate reading on small engines. This gauge correctly has the valves located in each of the adapter allowing you to accurately test small engines. ie scooters, lawn mowers, motorcycles, 4 wheelers and go-karts in addition to automotive engines. Plus the kit comes with spare valves.

I was very disappointed with this item after spending as much time researching all the brands. Once received, I could not get any of the connection to lock. There was interference in all of them as if the coupler was too small. Could not use and had to send back and buy local.

I have about 4 of these and this kit is great and accurate it’s not a harbor freight deal that will give you a bad reading of 60 when it’s 120 for a small outboard Get this one I had it for a few months now just keep it out of the cold the moisture will screw with the dial inside

I purchased this compression tester to check each cylinder on an old truck. The price was reasonable and the attachments were definitely a plus. This tester saved me thousands of dollars in properly diagnosed cylinder issues. I used on the truck, zero turn mower and Dirt Bike. Bike is a must so I will be able to monitor PSI and know when a top end is needed. Great tool, easy to use and money saver. I would buy it again.

Had to be replaced by manufacturer when the release valve would not work under high pressure. A+ for customer support.

I used this to do compression tests on my 12 year old Dodge Grand Caravan, and a riding mower. This kit is going to last a long time, and I think it is also very complete.

I purchased the VEVOR Compression Tester Adapter Kit to work on my 2016 JKU 3.6L and was highly disappointed. After bringing the engine up to operating temperature, removing the intake manifold, coil packs, and spark plugs, I found that the gauge would not register above 20 psi. I tested the remaining five cylinders—only to get the same results. I then connected the gauge to an air compressor, but it still failed to read above 20 psi. At this point, I figured the tool was defective. So I went to the local hardware store to purchase a different compression tester. After reinstalling the coils, spark plugs, and intake manifold, running the engine to operating temp again, and disassembling everything for a second time, I was finally able to get accurate compression readings—using a different product. This kit turned what should have been a straightforward task into a frustrating and time-consuming project. From my experience I cannot recommend this project, and if you planning on using this tool, I would test it first.
