I got the package with a well-stocked but unfortunately defective color cartridge. Apparently a problem with the contacts. After a brief correspondence via mail, which ran always friendly, I was sent to a "new" cartridge, which worked perfectly well. Only then I should send the defective cartridge back what me to demand the postage costs were reimbursed. So, a little back and forth, but in the end a satisfactory result and the customer service was always nice and responded quickly.
Both the black and the color inks make a good impression and provide reasonable prints. The print quality is minimal after the original cartridges back (sometimes with minimal banding). For the price a good product and a good service!
