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.

This Compression Tester Kit is excellent for examining small engines. It includes a handy 14mm adapter with a Schrader valve, ensuring precise readings in small engines by avoiding air hose issues. After conducting tests at the appropriate temperatures, satisfactory readings of 175psi and 185psi for each cylinder were obtained, aligning with the acceptable range. I appreciate the kit's quality and effectiveness. In summary, I like it..

I picked this up to replace the tired compression tester I have been using for years. I did a lot of rebuilding waverunners and riding lawnmowers, both of which have their own quirks, but I would have loved to have the adapters and flexibility that this one has. I tried it out on my John Deere tractor which is only a couple years old, so I new that it would have good compression. It took a little adapting, but I managed to use it to check the compression on that engine. The compression came in around 98-99 which is close enough to the 100psi I was expecting. The kit comes with schrader valves which leads me to believe I could use it for testing the fuel rail on cars, though I haven't tried it yet. I have a good tester for that, but it is nice to have this as a backup. Overall, a nice compression kit that seems to work well.

Higher quality than the box store house brands. Comes in a nice and large case with several adapters and hoses. I really like the solid ~8\" adapter end, great for those deep spark plugs. The adapters ends also lock so no more loosing them in the spark plug socket when using the hose to twist. Cleaver and not found on the cheaper box store sets. This Vevor brand of tools/equipment continues to impress me with its cost to quality ratio. I think there is real value.

First the case this set comes in is very nice with molded plastic to hold all the pieces in place. The latches aren't just bent over plastic that tend to break off but plastic latches that swing on a pivot which will last longer. The gauge itself has a rubber coating protecting all sides of it. The kit comes with quick connect adapters to make it easy to disconnect while you thread the hose into another spark plug hole. The quick air release button makes it simple to relieve the pressure before moving on to another cylinder.

Tried this on a motorcycle as soon as I got it and the gauge wouldn't hold pressure. It should hold pressure until you press the relief button just before the gauge however it wouldn't build accumulative pressure. Disappointed but they are supposed to be shipping a new one so we will see how that goes when it arrives. Fingers crossed that its not faulty. Also I'm not 100% sure about the hoses and sealing to the cylinders. Time will tell if I have a properly functioning item and can put it to the test for any amount of time.

so far so good only used it once on a small engine

The VEVOR Compression Tester Adapter Kit, is currently unused at my shop. However, it seems well constructed, has good/very reasonable ratings by others, will likely work well for our needs (usage expected within the next week). However, the plastic case that contains the various components is, very much, less that great quality. The carry handle is possibly the flimsiest and cheapest manufacture I have seen to date!. On the first day of receiving the kit, the handle on the case fell off. When I picked up the case by the carry handle, the handle simply came off. Inspection of the handle design revealed a very poorly designed handle. We will post another review after using the kit in the shop.

no adapter to come lose in spark plug hole
