Summary: This is a high-yield toner cartridge (2600 pages according to my manual) yet the price is low. It's probably the best reason to buy a Brother laser, the consumables cost is quite low. My MFC-7460DN's starter toner cartridge didn't last long, it's only printed 343 pages and it's half empty. Thankfully Brother doesn't soak you for a replacement toner cartridge. As to how it performs, it's toner! It makes a laser printer's pages visible.
