Works as expected. It is a protractor that measures angles in radians, in comparison to the more ubiquitous degree protractors.
This item works exactly as expected. It is a protractor with angles measured in radians rather than the more common degrees. If you are doing any work in science or engineering where radian measure is needed rather than degrees, this is what you probably need.
