Dear St1114_nj: IMHO and due that that cartridge has only four hours of work/play seems to me that it is almost imposible that cleaning with a brush any cartridge stylus could be broken off if the cartridge stylus is on " specs ".
It seems to me that that Ortofon stylus was not right glued and you have the right to ask for warranty.
Through the years I found with similar ( more dramatic ) problems: stylus cartridge ( in a new cartridge. ) that after 10 sg goes out!!! so what you experienced IMHO was/is a fault on that cartridge.
Regards and enjoy the music,
Raul.
