What's the word on BBB?

I’m new to the tri world and even more new to the cycling world. My bike has a Campy Veloce groupset. I got an extra set of wheels and I would like to get another cassette so I don’t have to break them down when switching back and forth.

Does anyone know what quality BBB cassettes are? They are definitely less expensive than Campy, but are they as strong?

Thanks for your help!
