I haven't had a chance to use this yet but it sure looks nice. I did notice one problem with one piece not lining up properly which would result in the angle readings being off a bit. The screw holes were located about 0.18 mm off so the edge used to align the angle measurement would result in a small discrepancy from the actual angle. If precise accuracy was required, the square that I received wouldn't be suitable for use. (see photos)

Very good quality for the price. The square is dead square in all directions (checked with a precision one). The ability to quickly get predefined angles is also very handy and more precise than aligning with the graduations.
