This little metal warrior has been living on my keyring for weeks, and I barely notice it's there - until I need it. The first time I transferred a 3GB video lecture to it, the speed made me double-check if I'd actually clicked 'paste'. Gone are the days of coffee-break file transfers!

The all-metal body has already survived two drops on concrete (thanks, butterfingers) and emerged without a scratch. It does get warm during big transfers - not 'oven mitt' hot, but noticeably toasty. Pro tip: That tiny keyring loop? Replace it with a slim carabiner unless you enjoy playing Operation with your keys.

As a professor, I've abused this in every way possible: left it overnight in a rainy bike basket (still works), used it as an impromptu screwdriver (not recommended but hey), and constantly yank it from tight laptop ports (hence the new scratch 'tattoos'). The COB tech isn't kidding about dust resistance - my bag's lint collection hasn't phased it.

Surprise MVP feature? That barely-there profile means zero 'USB bump' when plugging into my Tesla's center console. Though fair warning - at 256GB capacity, you might forget how much junk you're actually carrying around until you try to locate one specific syllabus file.
