How can I identify a counterfeit Xbox 360 controller?

Microsoft has changed the looks of its controllers over time.

For instance, my original wireless controller from my Elite looks identical to the images you showed, and says Microsoft twice on the top of the controller (one hologram, one etched in).

My newer wireless controller, that came with the Wireless adapter for Windows, is all black, and only has the hologram on the top with Xbox 360 etched in the top.

On both controllers, the hologram is right above the battery pack, so it may be located in a different location on a wired controller.
