Review on 🔲 XUNTOP Aluminum Cabinet Positioning Squares by Steve Campbell

I have many precision squares. I also have precision goniometers that are accurate to 0.01 degrees. Problem for your use if you're just trying to get closer to a square than they're good enough, if you use them for absolute squares they're no good. Too bad they don't have better quality control. Easily identifiable with optical systems or device checks Sorry, must stay true to the checking process.
