This protractor is a game-changer for industrial and scientific professionals. Through trial and error, I found that this protractor allows for precise and accurate measurements in a matter of seconds. The sleek design makes it easy to handle and store while being durable enough for daily use. However, the only minor con is that the markings can be hard to read in low lighting. Overall, I highly recommend this protractor for all woodworkers, fabricators, and carpenters in need of high-quality dimensional measurement tools..
