Over the course of several years, we had been successfully using these in our Brother MFC-L2690DW. They are not EOM, but they are very well made "compatibles" and they were saving us considerable expense compared to OEM. They worked flawlessly. Now the Printer itself has unfortunately failed and had to be replaced with a newer model which does not use these same drums and toners. So, these are no longer needed. If you use Brother Drum DR-730 and Brother Toner TN-760 you can save big...we paid Amazon $130 for these 4 items in July 2025, so they are like new. One toner and one drum were installed in the failed machine in August, and have very limited use...remaining life is likely 90%. The other drum and the other toner are still factory sealed and new. The complete list of compatible machines is too long to post here.
