Meet minimum standard. One was leaving dark spots at the start. The second one is ok so far.

We have bought these before. They are good as long as they are used quickly. Ones that we used after a year printed quite lightly. We thought our printer was the fault, but when we bought a new cartridge the printing was dark again. Our recommendation is do not rely on a shelf life of 2 years; use them during the first year and preferably in the first 6 months.
