Review on 📏 Precision Woodstock D4089 Machinist Square Set: Achieve Accurate Measurements with 4 Essential Pieces by Steve Yang

The squares were poorly packaged, fell out of the bubble wrap and I think got a little wrinkled in transit. The blade of the 100mm square flexes 3 full mm sideways from edge to edge, and the beam itself is diamond shaped at 30 arc minutes (I think the square they used to calibrate their machines was wrong too!). The 100mm and 150mm square blades are noticeably off-centre. There is also the problem of beam thickness. They were *not* as thick as advertised. I was so disappointed in the first two that I discovered I hadn't even bothered to inspect the two smaller ones. If zero stars were an option.
