What can i say? When faced with the choice of which toner cartridge to buy for my Brother 8460N, I just had to go with this TN-550. It was the obvious choice, particularly since it is the one designed for that model.
OfficeMax does offer about the lowest price for this cartridge anywhere, so with the MaxPerks thrown in, it is a great deal. I've never had any issues using this cartridge in my Brother all-in-one machines, and I support several of them.
