Boy, I'm not touching that one, other than ease of installation. Let's suffice it to say that my BB5500 and BB7700 experience does not contain the word "durable." I've had better luck with my BB6500, but none last as long as my Record loose-ball BB's, nor do they spin as well.

If the OP's example spins better and lasts 10 years, $100 is not bad. Cheaper than the one-season Shimanos.
