Compared to other printer cartridges I've purchased in the past the HP 950/951 give me many more pages per cartridge which I appreciate very much. The qualify is quite good and I don't think I've ever gotten such good quality photos out a a bubble jet printer before.
These cartridges provide the most ink for greater volume of printing than other ink cartridges I have used in the past. I am very pleased with this product.
I was skeptical about investing in a HP printer because the ink is so expensive however with my HP office machine and HP ink combo the quality is spot-on and lasts a very long time. I print about 50 - 100 pages a day and the black cartridge lastes about 3 months. The color cartridge lasted about 6 months. Previously I was changing the cartridge to my Kodak printer about once every 1 - 2 weeks. I don't put much faith in generic ink I've had bad experience in the past. Not to mention with the rewards system staples provides it makes the cartridges cheaper than anywhere else.
I am a teacher and a student and I do a lot of printing. This ink is great - It seems like I replace it once a month or so as compared to the smaller ink cartridges that I was replacing daily. I print worksheets and information sheets for my students and as a doctoral student I have been printing articles to read by the hundreds!! The documents come out clear and are easy to read. The articles that have colored photos graphs or charts are also easy to read and very clear. The is very clean. The best part is like I said before it seems to never run dry!
What I am disappointed is that I have not seen my rewards from spending 75 dollars or more on ink. I believe I have other rewards that are missing too. I do like the ink.
HP packaging is normally Blue for standard units and Green for the XL. This combination Blk XL and Std color a little misleading because it is Green. I will probably look at buying all XL's in the future for a better buy for the money. I have two of the HP 8600 series units one printer and one combo unit. In the 12th month now so far so good.
The HP ink cartridges are no mess easy to install and last a long period of time. My business consistently prints lengthy agreements and documents. The color cartridges last longer than my black but only because I use more black than anything to print. The cartridges are always available and if you return your empty cartridges to Staples you receive points for the recycling of the cartridges. Ink cartridges in general are expensive but these do last a long time so I think it is worth it.
