Logitech MX400 Performance Laser Mouse

I've been using this mouse for roughly 3 years now and it's still working like a charm. Easy to use and looks great even though it's quite old. I'm not using a mousemat or such but it doesn't decrease the performance and accuracy at all. The scrollwheel has a tilt function for scrolling to the left and right but this requires setpoint which can be downloaded on the logitech site.
