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.
“USB 3.0 speed is very fast on computers.”
“NWT, ideal for travel.”
