A Tiny Fast, Convertible Drive For Multiple Storage Devices, Is Perfect For The On The Go Presentation By Corporate Executives, Teachers Artist, Whom May Be Confronted With Unexpected Computer Ports.

Solid drive, flimsy cover.

The drive works great - as expected. It's compact and convenient with the two connectors. Minus 1 star because the plastic swivel cover doesn't work that well - it seems to want to pop off. I'd try the metal version if I was actually going to put this on a keychain.
