The built-in angle markings are dead-on accurate, making it easy to check my miters without grabbing a separate protractor. Feels solid in the hand, not flimsy like some plastic squares I've used before.

The 300mm arm is plenty long for laying out door jambs and cabinet bases, and the built-in angle scale means I don't grab a protractor half as often. Locked it against a 2x4 and the right angle held steady through all my pencil lines.

The 500mm leg gives me plenty of reach for marking long cuts, and it locks solidly at the angle I set. I appreciate the clear, stamped markings that are easy to read on job sites. I’ve used it to check my miter saw’s fence and it’s already saved me from a crooked frame.
