So for printing the product works fine but I found that the printer does not recognize them 100%. It may seem strange, but the printer will use them, but a "?" almost then because it knows they aren't real. I also had slightly less yellow than full. Not many, but I noticed when I replaced them all. It's been a few months now, I've used the printer a lot and I'm still not halfway there. On the other hand, I only printed about 76 pages (color printing is about 20 of them, and we're talking full color of the page). I love the product for the value. It saves me half the cost of a traditional one.
