The Techkey 128 GB MFi-certified flash drive offers versatile three-in-one connectivity and a rugged metal build, delivering fast USB 3.0 speeds. Its main drawbacks are the mandatory iOS app and the lack of detailed size/weight specs. Ideal for travelers and iOS users who need a durable, cross-platform backup solution.
The Vansuny 128 GB metal USB drive offers a rugged, waterproof design with a retractable USB-A connector and high claimed speeds. In practice, actual transfer rates are modest and the drive lacks a USB-C interface. It is ideal for outdoor workers and travelers who prioritize durability over peak performance.

Products in the top-left offer the best value (high score, low price).
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.
“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.
