Paeolos LC426 LC-426 Ink Cartridges Compatible for Brother LC426XL Multipack for Brother MFC-J4335DW MFC-J4340DW MFC-J4535DW MFC-J4540DW MFC J4335 MFC J4340 MFC J4535 MFC J4540W Printer (4 Pack)

These installed in my MFC-J4335DW just fine, they were recognised with no issue and ink levels show as full. Brother recommended shaking the ink cartridges 15 times before install. No mention of this on the Paeolos instructions but I did it anyway.Over 2 years before the expiry date on the cartridges supplied to me.Both Colour and Black prints are extremely close to the OEM inks, even on photo prints.It a fraction of the price of OEM inks I have no problems giving these 5 stars.
