Replacing an older "all in one" has been a rewarding experience so far. Having only four cartridges to replace instead of five is a good feature but the prices still are high and that's not an improvement. This was easier to install to the MAC but some of the Touch Screen features are confusing. eventually a "Voice command" would be an improvement. The biggest drawback is not having an optional tray for smaller Photo paper as HP has always been known for it's "Photosmart" advantages. Buying the Combination Color Pac is great except after a while it is hard to balance the usage of more commonly used colors. Giving a discount for buying multiples should be a way to solve this weakness. There never should be a point where you "MUST" replace but just select a different color would be a smart improvement as interruptions are very frustrating just to stop working because one color has been exhausted.
The yield on this ink is incredible! The claim is 2300 pages with the black but I have yielded 2500-2800 pages. I'm not really sure about the color yield but it definitely does what it advertises. I have made as many as 300 full solid color brochures for my business and still did not have to change the ink. I was amazed. There is no mess when changing the ink cartridge. It is easy to release the old one by simply pressing the cartridge once. The same goes for inserting the new one. I like to recycle my ink cartridges and there is no mess involved with these as with others. There is no leaking residue.
