I got this so I could use my 360 controller on the PC when i'm developing but in order to do that, everytime I want to use the controller on the console again, I have to re-sync it to the console.
This is quite annoying as when you pair the controller to the receiver, it unpairs with the console. Also, holding the guide button won't turn off the button. I have to unplug the battery pack.
Unless you have a spare controller you don't use all the time, it won't be so bad but I just have one controller and it's a bit of a pain swapping between.
I'm buying a wired xbox controller for pc instead, too much hassle.
Don't let me put you off, this is a great device if you don't use your main xbox pad with it.
