Rated 5 out of 5 by ARHPG from Excellent Value! Long Service Life! I bought a replacement 970 black cartridge for my HP Officejet Pro X576dw Multipurpose Printer, and it has given excellent results -- clear, well-defined black print for images and printing, and long life as a cartridge (there is an even longer-life version of this cartridge with more ink). Primarily, the ink quality in HP cartridges is superior to others in my experience, and I've tried quite a few others. Each time I return to HP quality and reliability in products, and now I only specify genuine HP ink cartridges for my printers. The HP 576dw MFP has been an excellent, durable printer, and the HP replacement cartridges have always given top-notch results as well as long life and excellent value.

Rated 5 out of 5 by MM65 from It works flawlessly. I have been using these ink cartridges for years on my HP Products and have never had to even notice they are there, only when they run out and I buy again. Mike

Rated 5 out of 5 by RiaScooz from Easy to Install I am very happy with this ink cartridge. I just inherited the printer from my office since we upgraded them to newer models. I was a bit shocked by the price at first but then I saw how many pages it will print and I understood the price. I’ve been using it every day since I received the ink and it seems to be doing great.

Rated 5 out of 5 by Bobbyboy55 from Black ink This ink is very black, and prints well. It comes in a convenient cartridge that does not bleed ink. I recommend it.

Rated 5 out of 5 by ARHPG from Excellent HP Quality This print cartridge consistently has high output and gives excellent print resluts. My HPx576d printer has worked flawlessly since day one -- and it is worked very hard -- and much of this can be attributed to the quality of the ink. I always use genuine, authentic HP print ink.
