Review on 📐 General Tools 29 Plastic Protractor: Accurate Angles with Durable Construction by Robert Diaz

Terrible design. The sliding arm completely covers the mark, so you cannot see the angle after the measurement. I need the EXACT angle to cut; I don't want to guess if it's 43 or 44 degrees. The return period passed when I finally started using this product, so I'll stick with this piece of plastic junk.
