Microsoft Xbox 360 Wireless Receiver for Windows "Official"
CUSTOMER REVIEW
There are many many wireless receivers on the market, but many of them require you to do surgery to get the drivers installed, as they do not have the correct (Microsoft) USB IDs for the official drivers to recognize them. You have to either edit the driver files, or force-load them, and the whole process is a big pain in the butt.
This offering does it correctly. You just plug it in, and if you're on Win 7 or later, the drivers automatically install, no hassle. If you're on XP, there's a driver disk included. After it's connected and the drivers have installed themselves, you just press the 'introduction' button on both the receiver and the controller, and wham, it's operational. No fuss, no muss, things just work.
I don't know with certainty that this receiver is actually made by Microsoft. It could still be a fake. But, if so, at least it's a *good* fake, coming with the right USB IDs, and a driver disk that certainly looks genuine.
There's no hassle, the price is reasonable, and the seller seems good. If you're going to buy a wireless receiver, this is probably the one you want.
