Aggregate ratings are mostly in the top two star categories, but a smaller one-star share shows that experiences are not uniformly positive. The evidence does not include review comments, so it cannot explain the differing ratings or establish how the ink performs in any specific printer. Check compatibility and treat the listed yields as claims with a stated coverage condition.
