Before buying HP printer ink set for jet pro I have half of level of all ink cartridges except BLACK. once I purchased XL Black in cartridge and inserted. All of other colors say DEPLETED. I DO BELIEVE HP programs inaccurate messaging through their small chips in the cartridges. So now I have to throw away all other colors. Will be changing printer to a different brand once ink is finished.
I always use genuine HP ink cartridges in my HP printer. Although they cost more I've never had a problem with them. They also seem to be long-lasting.
These toners are always work consistently providing with the most vivid color with long lasting use. i have been using these toners for years with never a problem. definitely worth the price.
