We have been using this ink for at least 10 years and have always been pleased with our purchases. We started homeschooling last year and I was afraid we'd have to start buying more ink with all of the paperwork we need but we have been able to use one pack for the whole year and even into the beginning of this school year. Great purchase just wish they didn't cost so much but that's out of my control :P
I bought this Ink mostly because I needed Black Ink and the store did not have just the 950 XL ink by its self. I do have the color inks. So I paid a big price for the Black Ink in the combination package. Next time I will probably buy on-line.
I have used other aftermarket ink. N G. Most printers know if you are using them. HP printers may send a message & 🛑. Also if you update your H P unit...be careful. Your unit may now reject all non factory ink.
