Following my first order, I see my long awaited happen without cartridges. I sent a direct message Colour answered me in the day by offering me a refund or new shipment ... having chosen the second solution, my cartridges quickly arrived and my printer J552DW recognized them without difficulty, everything works perfectly. Thank you to the seller for its quick reaction! I am prepared to recommend except that I just noticed that in the meantime, the price rose from 12.99 to 19.99 ... I'll wait for the blow a bit but it's not the only vendor whose prices suddenly soared ... it is still very advantageous compared with Brother cartridges.
