The only mouse i would recommend is the Logitech g500.

It's £40 but by far better than any other gaming mouse i have tried.
And it's actually fits in your hand, Matt finish so more grip, mouse buttons are reachable.
And you can pointlessly unlock the mouse wheel so you can spin it faster than the speed of light![]()
That about sums this mouse up, absolutly brilliant piece of kit. Also very sturdy so I can see mine lasting a few years.
