Review on 📐 Woodraphic Precision 12-Inch Measuring Tool - Guaranteed Accuracy by Donald Waller

I have tested this square extensively on several known "square" surfaces and it does not work at 90 degree angles. I also checked the holes with different measurements and this square is correct. Accuracy = to or better to a bright red overpriced brand. I've seen many reviews that said they were missing a pencil or allen key (both listed as included). I was missing an Allen key. I mean it's just a hex key but when you're paying $70 for a square you want EVERYTHING that should be included. I contacted the seller to say it was missing and was basically told to start the return process. Wow, for an Allen key? I think it should be customer service these days. In summary, outstanding, above-average customer service needs calibration.
