Pros: It works, but you need to fix it first. I think that it might just be able to plug and play on 32 bit Os's but for those with 64 bit os's it takes some work

Cons: IT DOESN'T WORK OUT OF THE BOX ON 64 bit Win7. FIX IS BELOW

Overall Review: THIS IS THE FIX FOR 64x: Right click on Computer Go to Properties Click on Device Manager Right click on the Unidentified Device (to determine which device, simply unplug and re plug, it will disappear and reappear.) Go to Properties Go to the Drive tab Click on Update Driver… Browse my computer for driver software Let me pick from a list of device drivers on my computer Windows Common Controller for Window Class Xbox 360 Wireless Receiver for Windows Version: 2.1.0.1349 [8/13/2009] Update Driver Warning Click Yes
