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.
“USB 3.0 speed is very fast on computers.”
“NWT, ideal for travel.”
Professional reviewers highlight the drive's very fast USB 3.0 performance and the convenience of having Lightning, USB-C and USB 3.0 ports in a single, rugged package, while noting that the mandatory BLANBOK+ app on iOS adds a setup step and that independent testing is limited.
Everyday users praise the drive for quick, one-click backups and seamless cross-platform file transfers, especially while traveling, and they value the durable metal build; no major complaints are repeatedly mentioned beyond the required app for iOS.
