I have ordered the cartridges Wednesdays morning and they were the very next day with me.
Meanwhile, I have black, blue and yellow replaced and everything works fine.
The cartridge will be immediately recognized by the printer and I can 'original' see no difference in quality in the print results on the cartridges.
A small Markel: The 'pull sticker' is really very difficult to remove and I have always with needle scissors, etc, assist.
Incidentally, I have the MFC-J470DW, Purchase Date: End of September
Strong buy recommendation!
