When I first got my 360 I tried using the wireless controller, but the batteries seemed to run out really quickly, plus the battery 'bump' got in the way of my fingers, so I went and got a wired one, but then I had a spare controller. Me being me, I decided to 'wire' it, so I bought a used P'N'C kit, tested if it worked without batteries, chopped off and smoothed down the bump, covered up the hole, and presto! 2nd controller!
