Returns true number pad codes. All of the keys send codes just as you would expect (no weird Alt codes sent for backspace, tab, etc.). Non-interlocking num lock, meaning you can activate num lock on this device without it affecting your normal keyboard (important for laptop keyboards). Well-built, like it will last a long time.

Mine also returns true numpad codes, however, due to Windows 7 limitations, you still can't do ALT-numpad codes unless you map ALT directly to the numpad somehow. It's more of a Windows letdown than a flaw of the product though. This is really a good, solid numpad that is perfect to go along with a TKL. I would say it has "class". If you like quality products that are attractive and not gaudy, then this is the numpad to get. Design and functionality are really well balanced here.

I just received mine today from the May 6th shipment, it returns true numpad codes.
