I did a first order which I was not satisfied, because the color ink cartridge Pixma MP150 was not recognized. After posting my unflattering opinion, I received a phone call from one (excellent) business offering me to send me two color cartridges and reimbursement. Finding that gesture, certainly commercial, but excessive, I wanted to receive the equivalent of my first order ie a black cartridge and a color. So this is what has been done and everything works well. For cons, I did not like finding my first comment deleted by them, as he had agreed for me to do (and I rectify) once the new shipment received.
