        As accurate as my veritas straight edge. But half the price. The tape measure is cheap but not needed for more than a reference so it does the job. Good profile, wide enough to stand on its own well. Overall very happy.

        Straight Edge Ruler arrived late and slightly “scuffed” at both ends due to incorrect packaging. The cardboard shipping tube was substantial and served its purpose. But the ends of the tube had been sealed with only two layers of clear packing tape, neither end of which survived the shipping. I was fortunate to receive the ruler at all since there was nothing keeping the 50” straight edge in the tube. Since I ordered it to level jointer and planer tables, not for measurements, the scuffed ends didn’t interfere with my use.

        Very good as a flat straight edge. The applied scale tape (inches) was not aligned precisely with the end of the rule (off by nearly 1/16 inch) -- not a big problem if you're aware of it but inconvenient for some uses.
