So easy to use. The included storage box is handy too.

Worked great. Reliable and repeatable readings. The case is a nice addition to store and carry the unit. The extension also made the job easier. I learned that if you set the cylinder at exactly TDC, the compressions reading can be done by one person. If not, another person is needed to hold the prop from turning backwards due to the pressure. This could have been explained by the directions...

Quality tester, nice to have the Master Orifice Valve to check the accuracy of the gauge. I vae seen many testers where the actual gauge is reading way off. This one so far is accurate as hell.

Super pleased with this purchase and I havent even used it yet. Could not beat the price and I need not comment on the super service I have always gotten from Spruce. The quality of the tester (I did fire it up with my compressor) is excellent and the inclusion of the Extension Tool was just icing on the cake and will be a great help during Annual. The case holds the tool and has a captive slot for the extension as well as an extra spot for a different sized plug adapter.
