The cartridges are properly and reasonably priced. Our two Epson Multifunction Devices Office BX935FWD be used professionally and recognize the cartridges without problems. There are also good for 4 months no clogging of nozzles, as we already had with other manufacturers. Consumption is also felt totally ok. So overall a great affordable alternative to the original cartridge - incidentally this applies in the same way for the color cartridges. Have fun with it!
