Edges have burrs that affect accuracy in certain positions. I had to clean it meticulously and carefully so as not to alter the surface where it was supposed to check for squareness. I bought another set from England for twice the price and it was well worth it. I really didn't expect much from 10β¬. mini square, but I also didn't expect to have to finish the production work. Overall, it's not to be thrown away, but I wouldn't buy it again from the same manufacturer.
