This is a very nice set with many thread sizes and two compression cones in case none of the thread sizes fit. The digital gauge is nice compared to an analog gauge because it allows me to check for the smallest compression leaks.
Had to buy extra to one to hold air

I needed a compression set to test an engine i was trying to save. This set was perfect at this price point. The gages are very clear and easy to read. They fit perfectly into the spark plugs, sockets, and so far they have lasted through several tests.They're pretty durable. I don't have anything to calibrate the accuracy to, but it feels that they are doing a pretty decent job of gauging the accuracy of the compression. When using these, I don't hear any air leaking out

This gauge is very accurate and has all the plug size fittings you need to check your compression. Even works well for your outdoor power equipment. A great addition to anyone's tool box.

I did not have any complaints with this product. It works just as I expected and has a good choice of fittings for spark plug sizes for the DIYer

Only a diagram for a manual and the written instruction on the back of it is all in chinese but the quality is decent. Great deal for the price, I used it on my '77 F250 and it worked great, it uses the M14 adapter in the kit. After doing some research i learned all vehicles use the metric thread for spark plugs even the old american classics which I was surprised to find out. Diagnosed low pressure in one of my cylinders, great tool to have on hand in the garage.

it seems to work well but I have no direct comparison
