Verified Purchase(What's this?)
This review is from: Xbox 360 Microsoft Authentic Wireless Pc Gaming Receiver for Windows (Video Game)
There's not much to say. This is the authentic thing (or a really, really, really convincing fake). It worked immediately on my Windows 8 rig.
Other products are cheaper and it might be tempting to go with an imitation. I say just go for the real thing.
