I feel like the quality of this ink has become lower. The most recent pack of cartridges I bought lasted less time then usual with the same amount of printing. I have also has trouble getting the printer to recognize the cartridges as well, the printer keeps telling me it cannot detect the cartridge. I had to take the little sensor chip from an old cart and replace the chip on the newer carts to get the cyan to work.

Seem fine, but printer cannot detect ink level with these
