Pros-The quality is great. Device works flawlessly. This tool will last you a lifetime. Easy operation for users with easy guide for the novice to assist with determining issues. The gauges are large and easy to read.Comes with a nice storage container to keep it all together.. Cons- The only Con worth mentioning is the length of the hose, although "NOT" a deal breaker it would greatly enhance the product further if OTC supplied a LONGER hose. Extremely satisfied with the purchase and would highly recommend it to anyone looking to purchase a "Reliable and Accurate" tester that will last you for years. Furthermore OTC manufactures for Mac and Snap On tools.

After reading the bad reviews On this leak down set, I was hesitant, but when reading reviews of other sets where most reviews were good, but B still had bad reviews, I decided to Go with OTC. Along with their compression test kit, I trouble shooted a cylinder 2 misfire on a V6. 5 of the 6 cylinders tested good, compression held on the gauges and were consistent and accurate to my air compressor gauges. Helped me diagnosis Bad exhaust valves for my misfire. Overall, very happy with the product quality, accuracy, and price point. I would not hesitate to but this again

The 10mm adaptor diameter is a little too big to fit in to the spark plug hole recess. I got it machined off .5mm to 9.5mm instead.
