Pro-Grade Quick Engine Compression Test Kit - Universal

Very quick delivery, gauge works well, easy to use for an amature like me, appears to be manufactured with good quality, case was a little banged up, but no biggie

Can not trust the readings, but just used it to compare cylinders relative to each other. The o-rings are fragile as well.

I waited to write my review, I make this purchase and from all my internet purchases this was the only one that came with a problem, not measures well compression as I tested different cars with different kits. I still have it but it not works fine.

I have used this item several times. great price, fast shipping.

very quick shipping ! great price! and work like a pro. Thank you !!

I used this "tool" once. It gave several low readings ....When compared to another proven guage this was 30 psi off on each cylinder. I believe it leaks around the coupler. Save your money buy a one piece guage.
