Yep, it IS a cable and... it works! You plug one end into something (like an external hard drive) and the other end into something (say your computer). And then lights flash and information is shared/exchanged. Very much like magic.
Now I have a three foot cable but like a lot of men I wanted something bigger. To impress people. I didn't have a lot of money. So I turned to the ComputerCableStore and they have restored my self worth by providing me with a six foot USB 3.0 SuperSpeed tool. Now I take it out and show it to everybody! Get one, impress your friends.
