At best I can say these are easy to install. I hate buying printer ink because it only lasts me for one use. Next time I need to print something I have to buy another ink pack. They cost about $30 with tax. So to print a few knitting patterns for my Mother I am spending over $30!
They say it lasts longer if you use it more often. But, that is impractical and senseless. Waste paper to preserve chemical ink packs/ cartridges? No thanks.
I bought one which promised it would last longer. It cost more, it did not last longer. Until they find a better way I'm not buying printer ink and not using my printer. I can pay a dollar to print a few pages at the local Shoppers Drug Mart. Far more cost effective and less non-recyclable plastic in the landfill. (I include the printer itself in that).
