Good tester for the money.

It did the job. It can be a little awkward to thread in the flexible extension, but that is to be expected. Not sure how tight to screw it in because it has rubber washers. So it probably doesn't have to be as tight as the spark plug. My single cylinder lawn mower tested at 20psi. Should be 60psi. FYI; I added a teaspoon of oil into the spark plug hole and the compression doubled to 40psi, which often means the rings are bad. However, my small lawn mower engine sat for 30-years, so it was actually the intake valve that was stuck open. Once I got it freed up, it ran fine.
