The Microsoft Xbox 360 Wireless Controller is bar none, the best controller I have ever used. In my life I have used NES, SNES, Dreamcast, PS1, PS2, PS3, N64, Gamecube, and the Original Xbox Controller and this is the most comfortable controller and offers the best controls for almost any given game. The wireless charge from a recharchable Microsoft Battery Pack can last about 25 hours and is easily recharged with either of the two options provided by my Microsoft. One kit allows you to charge the batteries like a normal rechargable battery station and the other offers you the ability to turn your controller to being wired so it charges from the sytem. The controller has 4 face buttons, 2 analog sticks, a D-Pad, 2 bumper buttons and 2 trigger buttons along with the Back and Start Buttons. The most prominent button is the Xbox Guide button located right in the middle that brings up system options and the ability to turn on/off the console, the controller and even revert to the Xbox 360 Console Dashboard. Finest controller I have ever owned, good battery life and comfort with great usability make this a sure winner.
