Products in the top-left offer the best value (high score, low price).
Professional reviewers highlight the Ultra Fit's ultra-slim, plug-and-stay design as its standout feature, noting that while it doesn't match the top-tier speeds of premium USB-C drives, its 130 MB/s read performance and bundled encryption software make it a solid choice for discreet, everyday storage. The consensus is that it excels in low-profile scenarios but falls short for power users needing the fastest write speeds or rugged durability.
Everyday users echo the reviewers' praise for the drive's tiny, unobtrusive shape and reliable media transfer speeds, appreciating the convenience of a permanently attached storage device. Common complaints focus on the fragile plastic build and the risk of misplacing the tiny unit, with several users noting slower performance when the drive is used on legacy USB 2.0 ports.
“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.
