Review on 📏 Versatile Metallic Protractor: A Must-Have for Designers and Architects by Adam Johnson

Very cool idea, but this particular tool lacks the ability to stick to paper. So if you watch the video try it yourself, the tool moves all over the paper and doesn't stay in the middle. I'm guessing that's the purpose as the bottle opener still works and the straight line tool. But don't buy it if you want pretty designs that are perfectly centered on the circle.
