These worked. I hesitated because let's face it, it's PART of the cost of the real thing. When they arrived the package was hot from sitting in the mailbox in the summer sun for who knows how long. Bad sign. When I took them out, both cartridges had ink spilled on the outside and the color sticker didn't quite cover the ink and it looked like it was leaking a bit. I cleaned them and installed them and wondered what the heck. Worth a try. I followed the instructions and just want to say that they are excellent detailed instructions with detailed troubleshooting tips. I had to do a "clean" function on the printer before I could get a good solid print. But bottom line, they worked and probably saved me $20 or more compared to real regular cartridges, but $50 or more compared to comparable XL cartridges. I would definitely buy them again.
