I appreciate the ease of installing a new cartridge. As a single user who doesn't install often, I find the little You-Tube videos helpful. The packages are so tight I ruined the first one so cannot return for recycle. I plan to take the used cartridges to a place here which recycles.
I print a lot of photos and cannot tolerate poorly refilled cartridges. HP factory cartridges work well, but are very expensive. Pictures use toner fast.
