Blah laser, led lights, tons of marketing bull****.. If you want really good gaming grade mouse with no extra bull**** included - get Zowie FK.

Well you have some point there. But for me what makes good mouse is simplicity without sacrificing performance. So in nutshell: - No need for software. - One of the best optical sensors on the market. - It works. No acceleration (sensor) nor lift-off problems etc. Just saying that expensive mouse with 100000DPI and other idiocracies typically won't make the mouse any better than cheaper and simpler ones. But basically. What does good mouse for simple end user - is it's shape.
