Logitech MX518 (mouse). I bought it for gaming as I was using a 400DPI free Dell mouse I had, I didn't realise what a difference it could make. They sadly stopped making it, I emailed Logitech pretending mine had broken to see if they had any internal stock but I got nowhere. I bought a Logitech G400S for work which is pretty close, but it's not the same.
