The magnets are not yet installed in the project. The project entails a curtain rod held in place by the magnets. The magnets require adhesion to an aluminum angle, and they are juxtaposed at 90°. I have not figured out how to hold them in place while being adhered. The magnets appear to be well made and they are very dimensionally consistent.
