I already owned a digital protractor that I used for measuring angles, but I'll tell you what, I actually like this one better. It's a bit heavier than I would have expected from an aluminum tool, but I think that's a good thing. Likewise, the motion of the arms seems solid, but not too tight. It's just tight enough so that it won't move once the angle is laid out. I didn't have high expectations when I ordered this, but frankly it's a pleasant suprise.
