Review on 4-Pack ONLYU Compatible Toner Cartridge Replacement for Brother TN760 TN-760 🖨️ TN730 - Optimized for HL-L2350DW HL-L2395DW HL-L2390DW HL-L2370DW MFC-L2750DW MFC-L2710DW DCP-L2550DW (Black) by Duy Desperado

They work well and are easy to install but I have found that the print is lighter than the original Brother -Cartridge. I had a Brother cartridge on toner save mode and it worked very well. But these new ones (others) were too light for this setting, so I just turned off the toner saver mode and everything was fine. So these cartridges are (each) (much) cheaper than Brother cartridges, but again I have to use more toner. But all things considered, it's probably cheaper to use these third-party cartridges than Brother cartridges.
