although the bells and whistles are sweet, most of them i dont use. I disable the software mods for my mouse and kb alot of the time. I go with how it feels personally. What you are REALLY paying for is the dpi. You may say...."well i don't need it" but the better you get (at say FPS games) the more you are gonna notice your 20 dollar or 30 dollar mouse isnt cutting it with the dpi abilities. Personally I always liked Logitechs mice.
