After my new printer (Brother MFC-J870DW) initially wanted to accept cheap compatible ink cartridges, I was afraid I would now always buy expensive original cartridges, but then I found this good cartridges whose chip was recognized without difficulty by the printer. I see no difference in quality for printing with original cartridges, at least not when printing on paper, photo printing, I have not tried yet. In addition, the delivery arrived quickly, so full marks!
