I have bought the cheap $30 compression test gauges and I can tell you, they don't work. Do NOT waste your money on cheap testing equipment. The cheap gauge i had before would read about 50-60 PSI on all 4 cylinders which I found strange considering it would run and idle fine. I spent hours diagnosing the problems that could cause the low compression. At first i thought it was the timing but all the timing marks lined up. Then I thought it could be the cylinder not sealing, so I bought a leak down kit. The leak down kit read about 10-15% on all 4 cylinders, which is acceptable on a 1980 Suzuki motorcycle. So after messing around for hours I finally gave up and bought this higher end compression test kit. I tested the cylinders with the new tester and BAM, all 4 were reading from 130-140 PSI. This is where I was expecting them to be. The moral of the story is NEVER buy cheap measuring equipment because you may be chasing your tail for no reason. Buy tools you can trust and count on.

I only used this once on an outboard engine. It worked great. It has a nice case to hold everything and protect the gauge when not in use. This comes with most of the adaptors you will ever need and instructions. I was able to test my engine a lot quicker than I thought as my local marine shop wanted to charge three hours labor. I was done in less than 45 minutes and most of that was figuring this thing out. This product has already paid for itself.

I'll caveat my review by saying I'm not a professional mechanic. Well, I did have dinner bought for me once after working on a friend's car, so that's sort of like payment. Not sure that qualifies me as a professional mechanic, though.I purchased this kit to work on a friend's car (a different friend, I have at least 4 of them) that had a suspect head gasket issue. I've always wanted a compression tester and this was the perfect reason to buy one. I own other OTC tools and I've been really impressed with them. Along with the other positive reviews here on Amazon, I had no hesitation buying this kit. OTC has another compression tester kit () that has fewer hoses, but it's only 10 bucks cheaper so I splurged and got this deluxe-o model.The kit contains all sorts of adapters and hoses so I'm guessing it'll work on just about any engine out there. It even comes with a little spare parts baggy that has extra valves and o-rings which I thought was a pretty nice touch. Kit feels solid and well made, and has a nice case to keep all the parts together.The gauge is covered in rubber molding to help protect it from any whacks and bangs during use and is pretty accurate. For what it's worth, I rigged up a contraption to compare the OTC gauge to the gauge on my air tank and they measured the same at 100psi. At least now I know the OTC gauged measures the same as the cheap gauge on my air tank.For me, buying this kit was sort of like a rite of passage. My tool box is full of all types of wrenches, sockets, ratchets, whirly-gig thingamabobs, etc., but this is my first real troubleshooting tool. You know, the type of thing that most people won't have in their garage. I'm feeling a little giddy.Overall, I'm very happy with this purchase and would recommend it to a friend--or in this case on Amazon, I'd recommend it to total strangers.

Tried 2 of the Amazon red box specials, junk. This one has an excellent build quality and gives consistent and accurate readings. It costs $100 more, but is worth every penny.

We are yet to receive the Input Tax Credit for GST. The supplier has not filed his return. This is completely unacceptable. Can you ensure this close at the earliest.Further the product and supplier both are absolutely pathetic.
