Review on Precision Measuring with Woodworking Caliber Marking Degrees by Evan Zurlo

The ruler doesn't match the center line so it's not a very good center finder. I had markings on the ruler in millimeters on one side and 0.5mm on the other, which isn't that scary. Apart from the poor workmanship, the material seems to be good. Unfortunately I have to send it back because it doesn't work as expected.
