Professional reviewers commend the Vansuny 128GB metal drive for its exceptional ruggedness, waterproof UDP packaging, and plug-and-play ease across platforms, positioning it as a solid value for its price. However, they consistently note that real-world read/write speeds fall well short of the lofty 400 MB/s claim and criticize the single USB-A interface as a limitation compared to newer dual-port alternatives.
Everyday users largely praise the drive's durability, waterproof capability, and convenient retractable design, especially for travel and outdoor scenarios. The dominant criticism centers on the over-hyped speed specifications, with many noting actual transfer rates are much lower and that the device must be dried after water exposure before reuse.
Professional reviewers acknowledge the C162's robust metal construction and lifetime warranty, but they criticize its severely limited real-world performance, especially the gap between advertised and measured speeds and the negligible 4K throughput, making it unsuitable for demanding transfer tasks.
Consumer feedback is sparse, but the available data suggests users are likely to be disappointed by the slow actual transfer rates despite the drive's advertised speed claims, while appreciating its compact, rugged design.
