The Smooth As Silk full shells for Xbox 360 wireless controller have been colored using a special process that makes the surface extra smooth and very pleasant to use for gaming.
They come in 4 versions: All Black, All White, Black(top)+White(bottom) and White(top)+Black(bottom).
All versions includes the Blue light kits (optional installation) that requires simple soldering to be installed.
The XCM D-Pad has been redesigned and optimised. The new XCM wireless controller shell uses a much larger D-pad with more room to allow the d-pad to move more when using it. This will make sure you do not accidentially hit another direction on the d-pad while trying to access something else. For example when switching weapons on most first person shooters.
