Gave consistent, repeatable results until it broke. This would have been acceptable, if it hadn't been for the fact that it quit working on the fourth cylinder of the first engine. I bought this one at twice the price of some others, specifically because it was supposed to hold up better. Not so much.

          Great product and the price wasen't bad. All Advance Auto Parts products should be eligible for all discounts. I'm all about shopping for the best deals and it is no surprise to me that nine times out of ten that either Advance has the best product or the price just can't be beat by their competitors. If Advance Auto Parts dosent have it on hand they will get it for you ASAP and the shipping is free if sent site to store. I have made a few bonehead purchases in the past by not getting the right part ect. and Advance Auto Parts has always returned my money with no hassles or attitude. I use my debit card alot and if I make a purchase with it and later return what I purchased, Advance with credit my account but it can take a few days, It would just be more conveinent to give me the cash instead of waiting for my account to be credited, I gaurantee I would be more inclined to spent that cash right then and now in that store. Sieg Hail Advance!

            Had to drill the valve end of the T-handle test tube.

            Got it home and bench tested the unit. Couldn't get air through the T-tube. Unscrewed the pressure valve and discovered that the thru hole was never drilled out.

            Basically a blind hole with the air valve screwed into it.

            Now seeing as it took me a couple of hours and 6 different stores to find this unit. I drilled it out myself.

            Used the unit for my compression testing and put her on the shelf.

            Oh well,,,,,,,, its been that kind of day.

            Other then that. Its a pretty nice unit with all the adapters you should ever need.

            Bought this tester to replace a old AdvanceAuto tester that I bought years ago & was suspecting had become inaccurate.
            This new tester works fine.

                  It screws into the spark plug hole and measures cylinder compression to accurately diagnose your engine condition. I would recommend having someone who is knowledgeable with this type of work or has used one before do the testing for you.
