A few comments- A poor fitting cartridge bearing can move about within the BB shell and this can and does cause noises quite often.

For three BBs to "go bad" (my term) in so short a time (notice I didn't say miles yet) suggests some basic issue is still present. Issues might be a poor BB shell factory finishing, and the bearings are not best held in place. Or so much environmental exposure (the simple example is riding in the rain or transporting one's bike outside a car during driving in the rain. Add salt or mud...). Or the assembly was poor (as in too much preload or not fully seated bearings). Or other stuff, including just way more miles a year than what the manufacturer designed for.

More data would be nice but nothing we can say will fix the problem. That's up to those who can actually touch the bike. Andy
