I have tried many different third party toner replacement products for my Brother printer with results ranging from terrible to very good. I was so frustrated that the last time I needed toner I humbled myself and bought the Brother brand which is outrageously expensive but excellent. I chose a different brand of toner and ordered MIRHO toner. Although the cartridge looks different than Brother brand cartridges, it fits perfectly. I only have 100 pages in these cartridges but I'm happy to report that out of those 100 pages the print quality is on par with the Brother brand. I have no idea how many pages I will print or if I will have print quality issues later, but for now I am happy with MIRHO's product and will let you know if there are any issues.
