Xbox 360 Keyboard and mouse?

[Tralius]

Hey all,
Was just wondering if anyone has tried out the XFPS360 to use a keyboard and mouse with an xbox 360? Im thinking about puting one in my xbox laptop but have never used one of these before. Is there any lag in the mouse movements? If anyone has used one before, any information would be appreciated.
Thanks

I don't own one but my cousin has one, ive used it a little bit. While I was using it I did not experience any mouse lag at all. It was very nice and was really helpful, you really gain an advantage over your opponent to be able to aim so quickly, plus sniping was a breeze. I would go for it if I were you.
Let us know how it turns out
