My brother bought me this mouse a year a go becuase cordless was the new thing and i don't have much space for cables on my desk. This is a dead easy mouse just hook up and use, the optical recogntion is'nt bad either but it does suffer when you batties start to loss strength, and htis mouse eats thou them like swiss cheese. and if your like me and enjoy your gaming to then this mouse can be a pain. when it starts to die on you in critcal gameing moments and you have to change the batties.
but other wise a good mouse, hint find somewhere that sells chap batties and your sorted.
