logitech all the way.. I have gamed with logitech mice for years.. This was what my first logitech looked like.. (and I still have one.. )
I am not saying microsoft mouse (I have owned several of them) is a bad mouse but it certainly is not as good as logitech mice.
Heck.. goto
www.logitech.com and look at the top of the line mice there..
compare that to microsoft top of the line.. Lets see.. adjustable weights.. adjustable grips.. adjustable DPI.. hrm.. Oh.. microsoft doesnt do those features..
One final thing.. When my microsoft optical stopped tracking because it picked up a single cat hair.. and I have to flip it over to clean it out.. hrm.. I dont remember the last time I have ever cleaned my logitech optical..
