Review on 🖨️ Starink Compatible Ink Cartridge Replacement for HP 970XL 971XL 970 971 XL for OfficeJet Pro X576dw X451dw X476dw X551dw X451dn X476dn Printer (Black Cyan Yellow Magenta, Pack of 4) by Matthew Mosley

This is MUCH cheaper than HP but took more work than expected. When new cartridges failed with numerous error messages, their instructions were to download and install new drivers. After I did that and failed and played around a bit more, I contacted them again and they said they would send a new set of cartridges free of charge. Although I didn't hope it solved the problem. So for personal use it was worth turning off the printer for a few more days and wasting time because they are so much cheaper. However, for business use, you can certainly choose a more reliable HP replacement.
