Review on Imphomius 64GB Metal exFAT USB 2.0 Flash Drive - Waterproof, Dustproof, & Keychain - Gold by Brian Vasquez

This tiny USB stick is a miracle! The operation is perfect: just plug it into a USB port, copy your important files and rest assured that the sturdy metal case will not crack, damage or lose your belongings. There are also no moving parts, so nothing can be damaged. Hard to believe that it actually holds 128 GB. That's about 1/3 the size of my 32GB hard drive. The key fob helps you not to lose small change. My only concern is that some dust, lint or other debris will get in the hole and not be able to get out. A clear plastic sleeve over the tip would be a good idea. But I love this stuff.
