I am a professional user and was very disappointed with this tester. I owned one for several years. The joint between the hose & the threads came loose, and would spin, so I was not able to thread it in tightly. There is no o-ring above the threads, it does not seal well. The hose is too soft and flexible, makes for inaccurate readings. I just bought a Lisle 20250 tester and am very pleased with it. It was a great day when I threw this K-D tester in the trash bin.

This product works as advertised. Note that this type of compression tester is a little more difficult to use than the "press to snug fit" type, which must be forcibly held against the spark plug opening by one person while someone else cranks the engine over. This tester is a screw-in type which is what I specifically wanted. It takes longer to get a reading from each individual spark plug obviously, but has the advantage of being a one man operation and I think you get a more accurate reading. It has worked well for me.
