Have you tried flipping it around to make sure it doesn't fit the other way?

Summary: I have no idea what's wrong with some of the people giving 1 star reviews. This is the BEST usb drive I've ever had simply because of its shape. It is exactly the size of a usb port. There's not extra fancy cool swaggy plastic decoration on the thing. It can squeeze easily into the 1 free usb port surrounded by other stupidly shaped usb flash drives. I've had one for about a year, keep it on my keychain. It's been dropped scores and scores of times.
