Yes I've only used the one that came with my Hakko soldering iron, and I just got a replacement from Hakko since my old one is getting pretty full of solder bits.
The tip on my soldering iron is perfectly fine though.
The 599B is a Hakko assembly that combines a (kind of cheesy-looking) gold-anodized, thin, stamped, aluminum housing and one of their brass wool inserts.
AFAICT, it works well with all soldering irons. I certainly haven't noticed any detriment to my soldering irons over the >decade I've used it. It really seems to be fine and it sure is simple to use.
(I really have needed to buy new brass wool for a few years now, though. It works, but it is not nearly as slick-and-clean to use as it once was. Sourcing this from Hakko directly seems like a safe route and it's probably cheap-enough -- maybe I'll buy a few refills and have some for the rest of my life.)
