The angles have a good quality and not overly disturbing burrs or sharp edges. The holes have both inside and outside slight depressions on the edges, so that can be sunk screw heads. However, the centers of the holes and the wells are not always clean set, so at some angles minimal offset can be seen. However, this should not be a problem in practice. The "practical bucket" was in my case completely demolished already in the supply and no longer usable, but what I do not really matter. A total of four stars for a decent bracket set. A manufacturer's notification to the hole diameters could not hurt.
