Review on CASTOOL Digital Aluminum 0 230Degree Protractor by Anthony Grover

I needed a corner finder to stick the bar on the walls at a weird angle. This tool allows me to quickly and accurately determine the angle of a wall, which I can then use to make the correct miter cuts. Works for both inside and outside corners. The tool also allows you to fix the angle value so that you can move it and read it at the appropriate viewing angle.
