So far these speed squares have been as expected and for the price you can't beat them. The only thing that strikes me is that while one of the two pieces is perfect, the other has a series of ridges on one side and pockmarks on the other. Burrs are easily removed with a metal file. It would be a good idea not to remove these burrs before using the corner. This is the only reason I downgraded the product rating by one star.
