I'm using it for prostreet and dirt also..
but it is sucks for gear of war, kane and lynch: dead man, crysis, and more..
i think for action game or racing game is ok..
for game that has a mouse point is sucks..u'll find mouse is even much faster and convenience to use..

I have one anyway, wired version..is not worth to get the wireless...
rm180~199, for 1 year warranty only..

Although it's microsoft products, I dun have much confident on it..
I have one microsoft keyboard, it is sucks.. and a older microsoft product, the sidewinder gamepad, right after 1 year the gamepad rosak liao..

this time I buy 360gamepad bcoz it looks nicer than the logitech one. the logitech one looks very china product..

chillstream is not very expensive only..the wireless still expensive..
wired one is only 100~130
