I have always been a HP user and I must say I seem to get more yield from this sort of ink cartridges than I have had with other HP cartridges I have used.
Finally HP has put together an ink package that includes both a high capasity black cartridge and the colors needed. The combo pack should be priced lower but Staples ink rewards and ink discounts brought this combo package down to a more reasonable price.Because I had a coupon for 20% off I could NOT use my special Staples Ink discount card which when I purchased it I was told I could use it every single time regardless of how many coupons I had. Disappointed but still this cartridge pacage makes the trip to Staples easy and fast
I've been buying HP printers and new HP ink for 20 years and have found them reliable and high quality (and I've purchased Lexmark Brother and Cannon printers/ink in the past). I write in gray marker the date of each color's installation and have been averaging around 3-4 months between replacements on each color including the large black cartridge. If you ever have a problem HP has very thorough diagnostics on their website that will help you with cleaning your ink jets re-aligning them and or replacing internal ink jets.
Small size which lasts longer than any other cartridge I've used on any other printer. Warning that Cartridge is running low so that you can be sure you have time to make sure to have a replacement on hand.
