This is a well made, sturdy protractor. Metric and imperial measurements are accurate and square. I had trouble holding my square in the photo with one hand because the ceramic magnet is strong, but it's square. Complaints about the arrival of defective products relate to couriers and really rough handling and crushing under an avalanche of other packages, not to the quality and accuracy of the product. I definitely recommend this product. It is very well made in the United States and has high quality control standards.
