What worse they all but quit making the square sockets. 12 points sockets are basically useless on the squares. I got a few 8 point sockets which are better than the 12points; though, not by much. I am still search every once a while for the 4 points. They usually show up under military surplus and can be pricey even when used.
I still see a lot of the square plugs when it come to plumbing.
