At least in the old days, when the socket pieces cracked, they would not crack fatally (you know, on the base of the arches), just at the center of the arch. Ever since they came out with the smooth variety of socket piece, the cracks have been more frequent and lethal more often.

I mean, I can stand it if only the top of one of the arches is cracked, but breakage at the base RUINS the part completely. It's immediately garbage. Otherwise, I may still use it for some guy who doesn't need very tight joints to be able to stand up.

Oh, well.
