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.
