I can not complain. The black cartridge is indeed (Canon MP140) does not recognize my printer, but a short e-mail traffic and 2 days later replacement cartridge, which was detected immediately and also works flawlessly.
I can weitermpfehlen the company only as well as the customer service is great and everything went without problems. I thank you for it and will certainly be the cartridges if they are empty, buy here on. Thank You
