The best thing about this product is its price. Compared to the squareness of some recent 1-2-3 blocks, the inside squareness appears normal on the inside compared to the outside squareness, which is clearly mismatched. The tool also has a number of visible manufacturing or manufacturing defects indicative of the build quality. I have tried to give examples of these imperfections in the attached photos. Given the condition of the product out of the box and its apparent inaccuracy, this is not a good investment. However, two stars instead of one because it is affordable. And when polished, it turns out to be a beautiful and stylish paperweight.
