Professional reviewers consistently commend the Power 128 GB card for delivering near-spec V90 speeds, robust shock resistance, and an industry-leading lifetime warranty with fast replacement. However, they also note that real-world write performance falls short of the advertised peak and that the card's advantage diminishes in UHS-I-only equipment.
No direct consumer reviews were found; most online listings only repeat retailer specifications, so everyday user sentiment is largely unavailable.
