Review on 🖨️ GPC Image 15-Pack Compatible Ink Cartridge Replacement for HP 564XL 564 XL - DeskJet 3520 3522, Officejet 4620, Photosmart 5520 6510 6515 6520 7520 7525 Tray - Black Cyan Magenta Yellow by Scott Ward

These little things work great in my HP All-in-One. Excellent quality, not inferior to the original, but many times cheaper! Almost makes me less grumpy about kids who don't know how to adjust print settings so they don't use up all the color inks. That definitely makes HP's arrogant programming a gem because it doesn't use "genuine HP products", but it still works fine once you hit the "shut up" button on the screen. Maybe it was "I see," but it doesn't seem that funny. Another plus is that they don't dry out as quickly after months or years in the box. Wanted to put in one of the fancy HPs which was maybe 2 years old, still sealed in the box and drier than King Kings underwear. I had the last one from a previous order (same brand, different range) which was maybe 18 months old and still visibly full and runny. Another great advantage is the transparent cartridge case. The factory ones are black plastic, so you need to use "Check ink levels" in the application or on the printer. You can simply open these above and simply look at them. Hopefully your eyes won't lie to you that the cartridge is empty when it's not, so now your second child won't go to college either because you spent their tuition on ink. Not to mention these cartridges will help your kids get into an Ivy League school, but they can print application forms!
