@bizz only problem with the G700, although its wireless you'll end up using it as a wired mouse if you're on the 1000Hz polling rate... my wireless adapter has been stuck in the mouse, like since last year jan....

depends what surface you're using it on. if its flat table like that, no big bumps in the surface or sharp pointy things sticking out of the surface (although it would be strange that you're using that surface in the first place) then the mouse should be fine... the feet might wear out a little quicker, but by then it could be time to change to a new mouse...

Just note that the surface will affect the performance, you might not get consistant acceleration/movement while going over a different surface (color, material, etc.)
