Compression tester worked as expected, good regulation of input air pressure, sensitive and stable readings.

Didn’t fit Rotax 912 ULS. That shouldn’t have been a big deal. I called and asked what adapter I needed and ordered the part number the tech gave me. That adapter fouled the threads in the head (wrong size, not technique) resulting in the need to replace the cylinder head.

Nice unit. Works as designed. Put to use day it was received following Continental M-O procedures to establish lower limit.
Impressed with quality. Worthy purchase and great for mobility with case.

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.

The kit arrived on time and in good condition. It is nice to have both the standard plug fitting for tight spaces and the extension tool for longer reach. The hard case is durable and has snap-in recesses for the various parts to hold securely.
The instructions were clear and succinct. The tester worked as intended and was easy to use. Would definitely recommend to others.

So far so good. Awesome tool(s) and case. If there isnt something already, I think it would be the ULTIMATE kit if it came with or if able to purchase an attacment that is a flexible hook with some length to it on the back side, and ALL orifices (short and extended) that are needed for all GA Power Plants including Franklin engines. One could make those tools, but they probably wont fit nicely together in the case. Very glad I purchased this tool kit.

This compression tester does the job just fine. The extension helps on some engines where baffling and wiring makes the plug hole difficult to get your fingers to to install the normal plug adaptor.
