Aggregate ratings lean strongly positive, with a smaller spread across lower star categories. This offers a limited indication of overall reception, not specific customer experiences or proof of transfer performance. For buyers choosing a 128 GB card for a compatible camera, the listed format and speed classes are more useful selection criteria than ratings alone.
