The workmanship is very good. During installation you have to watch something. The cartridges have a plastic closure as the originals down the ink outflow. This must be removed to insert the cartridge into the printhead. An adhesive tape at the top probably closes the vent hole. If the tape is removed, the cartridge tends to drop. I remove the tape from the top most recently directly when inserting into the printer.
I print until now mainly photos on photo paper and greeting cards (some with photos) on plain paper. Both the photos on photo paper and the prints on plain paper have very good quality. Had no problems with blurred ink by too fast or too slow-drying ink. Am absolutely satisfied. Whether the images even after a long time yet, I can not say anything to keep their quality for such a short time. I also had no problems with dried ink nozzles.
Whether the quantity of the print result of the original cartridges equivalent I can not estimate. Have a lot of photos printed and was ever excited as long the cartridges. The printer has quite early, the cartridges are low on ink. (Probably anyway a message from the printer and has less to do with the cartridge.) Can not be fooled. Have after the first message determines 20-30 photos on plain paper printed before then actually get the message now is empty.
Cartridge drips like when inserting.
Could the cartridge order only as a whole set. The cartridges are empty, depending on the use of different. Would prefer the colors specifically put together.
I would buy the cartridges at any time.
