I have purchased these cartridges for years for my HP Photosmart 2570 printer. Unfortunately, the last two color ink cartridges were rejected by the printer as "not compatible with this printer". Annoying, but I was sure it would be immediately remedied after contacting Monoprice about the problem. Much to my surprise, especially after receiving excellent customer service in the past, two emails sent five days apart have gone unanswered (the last email was a week ago) and I'm stuck with two ink cartridges that don't work.
PROS: Satisfactory, when they work
CONS: Don't always work and last Monoprice customer service is unacceptable.
Friend gave me a printer. Wanted to check it out without investing in OEM cartridges. Took a couple of tries to get the printer to recognize the remanufactured ink, but eventually they worked. Cheap investment for a backup printer.
Had this C8766WN (95) color installed for about two months and now printer displays"Remove and check color cartridge". Did this multiple times cleaned contacts on both cartridge and printer without any luck. Checked operation with a empty genuine HP cartridge with no problems. Monoprice cartridge still half full. Had another Monoprice cartridge in the pass fail right out the box. Cannot recommend this product to others. Product used in a HP Photosmart 2575xi.
PROS: Good price
CONS: Remanufactured color cartridges from Monoprice aren't reliable.
